Head Height Adjustment Cassette - An Easy DIY'er

I copied this section out of a vintage Sony SM, but the procedure is applicable to just about any typical mechanism. The head height adjustment cassette is simply a good, clear-bodied cassette shell with a few areas trimmed away to allow better viewing. Also in the procedure is a guide to adjustments on this 3-head mechanism in order to eliminate tape curl.

Making one takes about 15 minutes with any cheap ol' clear shell toss-out.

Enjoy!

hi all,
i saw this post and it brought back a re-occuring nightmare for me. the drawing is from (or the same as) a TCK81 SM, i had ocasion to replace some damaged parts on this machine, this meant removing the heads and block.

i looked at this drawing in the SM and did not give removal a second thought, looks straightfoward enough thinks i, takes the whole lot out. replaced the parts alls well until i have to set up the heads, prepare the tape with cut outs. (great idea).

Then low and behold the assembly particularly the head block has changed shape sometime in the production run. and that critical measurment of 9.1mm and 16.1 mm did not hold true on my particular machine.
i had a devil of a job to get the adjustments right. i wish i had measured the distance before hand, manuals are not always correct are they, lesson learned.
i since have seen a few of these machines all have the head block as the manual, trust me to get an oddball

Perhaps it was a TC-K75, the pre-cursor to the TC-K81. They looked identical except for the power switch, and I've seen two different versions of the power switch on these. The -K75 also had F&F heads instead of the better S&F heads.

In case anyone wants to see how simple it is to make one of these, I made two while tracing a tape-curl issue. Each one took ~10 minutes from start-to-finish. I used the cleanest clear cassettes I could find, in this case a new Maxell UR and a Memorex dBS so I could see thru the tape shells at the inner workings. I used a Dremel tool with cut-off wheel, but a small knife/X-acto would work fine also.

When you're just learning about tape decks, these are quick and easy projects and fun to watch the inner mechanisms at work.
