Tandberg 64

Decided to play around with one of my Tandbergs from ye ol' junk pile. This is a model 64 which is all tube, single motor, 3 head (No Crossfield on this model). This one was from an original owner and still has the case with keys, original TU spool, spool holders, manuals etc. The capstan idler was froze up so I gave it a complete clean and lube. The figure 8 belt is present but slips but will still FF and REW if you give it some extra time and a push every now and then. I will order a belt for it. The pinch roller hasn't turned to road tar and seems usable. Brakes work fine. It still has the felt damping inside the capstan flywheel. Thats fallen out of all the others I have. Heads look nice. And the Telefunkens haven't been harvested! Only turd in the punchbowl is someone engraved their VA license # on the lower head cover. Someone must have changed the pulley from a 50hz to 60hz one at some point because they put a Dymo label that says "60" over where it had said "50".

Some quick pics:

I love these decks. I fall asleep waiting for tapes to rewind though.

True they are no speed demons but they are gentle on old brittle tapes that the Crown's would turn into confetti ....
That and they sound damn good also.

Nice unit. I have a few series 15s which use the same 8-belt layout and believe me, with a new belt those things fly. In fact I'd dare to say that they're the fastest wind I've seen on a non-DD transport.

I would suggest you replace that yellow electrolytic cap on the left side of the 'innards' shot, if it is wired across the mains. Almost certainly past its best by now. Also any Rifa caps across the motor or power switches, had a few go up in smoke of late!

The new belts arrived today so I took it apart again to install them. While I had it open I also cleaned all the pots, switches and tube sockets and tested the tubes. All are good. I have yet to see a tube test bad from a Tandberg yet. I think it is because they all quit working before the tubes got enough time on them to get weak. I also took the motor apart and clean it and lubed it. This one still had the shield over the boards. This is often missing as people are to lazy to put it back after checking or stealing tubes from them. The counter belt had turned to goo.
Here is a tip for when you change the figure 8 belt and it still wont rewind or it slows down and stops. You will find its not the belt. To fix it you must remove all the tape guides. You will find the outer 2 in particular will have crud built up and burned into the top and bottom where the diameter gets bigger. This is enough to catch the tape with enough friction to stop it in rewind or FF. Another symptom is if the tape keeps wanting to loop up inside the head cover just before the far right guide with the switch wire. You cannot just clean it with a cotton swab it won't get it. I had to use a dental pick and a toothbrush. This was a very common problem with these. Also when you have the guides off it is easier to re-bend the stop switch wire so it works properly. These always get out of whack. Some people just jumper over the switch. So before replacing the belt check the guides first.
The last pic is the heads before cleaning. That is not a scratch on the play head, just some spuz. As you can see someone put a new pressure pad on top of the old one for the erase head. That made to much pressure and caused it to not spin up when put in play sometimes especially on 1.875 ips. This was already a very clean unit otherwise. Even all the rubber grommets between the unit and wood case were present and in good shape. The lower ones are almost always missing because they tend to fall off when people open them up and they don't notice or bother to put them back. It all works great now!

That for the pictures. This brings back memories as the 64x was the first tape deck in the house. My brother bought one used back in the early 70s. Very nice sounding machine and being a youngster it did not exhibit many of the issues you have resolved on your machine.

Tandbergs so make excellent recordings.

Since Dave mentioned someone put a Dymo tape on the outer case label to indicate his unit was for 60Hz, does someone know how to convert that back to 50Hz? I have several 64's with me that are all marked 60/50 Hz 117-240Volts, but the machines are all set up for 60Hz. I have to use frequency converter to use them.

Thanks!

Terence

Hi Terence!
The only thing that has to be changed is the motor pulley.
Well, good luck in finding the right pulley.
My first stereo deck was the 64, but an earlier one than yours. It did not have a "cross" stick shift; rather a "T". There was no 'free' position. There was also no end of tape shut-off. The fast forward was weak because of a design flaw and when I wrote to Tandberg in Norway, they responded as if I had the more recent version-like yours-and I pretty much had to live with this flaw.
But it sounded really good!
All the best,
Leon(The Audiomayvin, Montreal(514)739-5403)

Brings back memories. When I was a kid, my folks had friends who would lug their Tandberg over to the house and dub vinyl off my parent's Telefunken console stereo! They would sit and jabber for hours while chain smoking their cigs!

A customer of mine gave me a "64" a couple of years ago - but unfortunately it had suffered moisture damage. It is repairable however - We all get spoiled with multi-motor machines as far as tape handling wind speeds, but the sonics on the old Tandbergs are very good.

That is a nice looking unit for supposedly being on the 'junk pile'...I suppose it's true one mans junk in another's treasure.

Dave you come up with some of the nicest, oldest rarest unseen jewels of anyone here. How did you ever end up with so much gear? I doubt there is anyone around with as much stuff as you have, and the best part it isn't junk, it's stuff that is worth money and most of what you have I doubt anyone has a nicer version.

Perhaps you should open up a vintage stereo/audio museum and charge admission.!! Many (nearly all) of the pieces you have and post photos of look and seem like museum quality..best part is they work, in some cases better than new and may be the last working versions out there of some..

I've said it before, your gear posts and articles are always fascinating and entertaining. You and Pacific Stereo always have the best audio porn..

I dont they are that slow when doing FF or Rewind. They are mostly up to par with a Akai GX-4000 in speed i think. (That deck is newer)

Also clever design using the large round belt. Even the internal speakers sounds good. Nice little units. For a 1960s retro hifi they perform quite well.
Sadly they also suffer from that drive wheel problems, and the speaker foam tends to rot as well.

I'm currently working on yet another grey top tandberg, and as with the rest the main problems seem to be:

-Hardened grease on linkages off the joystick - this may well be difficult to shift or not returning properly to neutral. Check these where they lift the spool tables to engage brakes. Clear away any solidified yellow grease.

-Belt. If it is the original you will see small hairline cracks usually where it has 'elbows' from being in contact with the motor pulley for a long time. If it hasn't snapped yet it soon will do. Note it should cross over before the pulley on the supply side, with the belt coming from right to left on the upper pulley step.

-Rifa suppressor cap on stop switch s/c (needs a 47R in series with new x2 cap)

-Pinch roller arm actuation pivot - clean off old hard grease in the slot, and relube. Especially if it won't retract properly. Be careful not to let any grease drop onto the capstan flywheel visible below!

-Contacts on rec/amp/pb mode switches (common problem). clean with a q tip and switch cleaner, activate, then flush again.

-Spool backtension adjustments.

-Capstan idler. Often needs resurfacing if noisy running in playback/rec.

Sure I'll think of a few more things to check, but these are the main ones...

I haven't worked on anything, not even my own stuff for quite some time. My vision that was already damaged by a stroke years ago got even worse due to cataracts and got to the point I couldn't even qualify for a limited drivers license anymore. My eye doc has me wait a year to have the cataract surgery to make sure my eyes were stable enough from the stroke damage to withstand the surgery. Well for a couple weeks I had the best eye sight I'd had in years after the surgery but then the vision in both eyes started to fail. The retinas in both eyes stared to delaminate from the abuse from the surgery. My eyes will never get better ever again and at this time its not known how bas my vision will get until the new damage runs its course.
This is why I haven't been posting about new projects in some time. I am going to sell off most of the decks I own except for a few favorites as I know I will never ever be able to get to the others now.

Dave, I am so sorry to hear this news. I can understand how difficult this must be for you. I have diabetes and have received laser treatment for diabetic retinopathy which can also threaten vision. I don't know whether you have saught the advice of a retina specialist to evaluate your case but if you haven't, I would strongly recommend doing so. The doctor who has been treating me is Gilbert Grand at the Barnes Retina Institute here in St. Louis. He is one of the best retina specialists in the country and if you are able to, you may want to contact his office about having him evaluate your case. I have attached a link with his contact information. I hope you haven't given up hope that there is something that can be done to save your vision. Please let me know if there is anything else I can do to help.

Dave
