If anyone needs spare parts PM me. My 238 has fatal problems in the power supply and motor that will cost me more to fix than the deck cost me and I would love to help someone keep theirs running. My life just hasn't been the same since my 238 died, and I sold my 488mkII when I got it because I figured I didn't need 2 8-tracks Sad

Still have a 234 in pretty darn good condition. Although I've transferred everything of consequence to HD. I keep it clean and actually run it now and then to keep the thing loosened up.
It does have a pleasing sound to my baby boomer ears.

Seriously, i'd wear one of those. Until i'd rotted the armpits right through. I picked up a 234 last year and love it. You can push the tape soooo much harder than a standard 4-track.

When this thread started, you could buy cassettes at 7-11 apparently.

so, speaking of the infamous capstan motor, does anyone have a schematic? digging into the deck, it becomes pretty quickly apparent that the circuitry, not the "motor" itself, is what fails. i keep on putting off shelling out $100 to get a new motor for mine because i remain convinced there must be one of those little dinky resistors or diodes or whatever else is on that board that i could replace for pennies... but without values, nowhere to start Sad

Hi!

Actually, I think it's the little SMT caps on the controller board that fail. Here's a guy who done some groundwork and come up with a fix:

http://thesquarewaveparade.com/tascam122.html

I have a dead 122MKII and a 238 in the garage waiting to try this on, but I have yet to work up the courage.

BTW, big +1 on the 238! I've got mine racked-up like an oversized portastudio--a 238, a patchbay normalled to a Rane SM82 mixer, and an ART TubePAC mic-pre/compressor, all in a six-space rack. Perfect for demos or simple tunes, then bounce-able to DAW for mixing. Cool

Regards,
Joe

Nice find Joe!




..And about the second shirt design. Enough interest for maybe a short run via someplace like this?

http://www.uberprints.com/studio/

(hmm.. that image definitely wouldn't blow up cleanly which means a picture of the unit taken but without the cool metal reel to reel cassette.
Any chance someone is able to provide a high res picture of the original brochure? )

Edit: like this one. (thanks Jeff Peletz, homerecording.com)

Yes yes, thank you, why didn't i think to search for other units using the motor. ... SMT, man i was looking and looking for that term when i posted earlier. The main reservation i have about the fix, is that he's fixing the all-too-common runaway speed thing, whilst mine's moving sloooooooooowwwwwwwly. that'll at least be something to start on though, perhaps one of these days i'll finally be able to fire up the 238, 246, and 388 simultaneously, switch on all the dbx and interconnect everything with yet more dbx, so i can drift and bounce on the resulting waves of tas-fi

Well, the fix-it guy (Steven) says the caps fail "closed" decreasing capacitance and speeding up the motor. But caps can also fail "open," which could increase the capacitance, and could slow down the motor. So it's most likely the same problem, bad caps.

Regards,
Joe

That was my observation also.
I used to hump the damn thing all over hell and back, just having a ball recording friends. Once you figure out how much to push it to get the desired amount of trash-itude it‘s a fun machine to have. Have you tried mixing down to it? Left =1 & 2, Right = 3 & 4
