[sdiy] Teac Trivia

[phillip m gallo]

Gene,

If the 2340 is the 7" reel version of the old 3340 then i can guarantee a
hysteresis synchronous motor was used and that people back in the '70's
successfully made vary-speed capstan drive for it's big brother 3340.
Sanken power amps where popular for this as i recall.

regards,
p

Hi DIY,

Sometimes I get strange ideas... I want to do some tape flanging experiments
so I was wondering if anybody out there knows whether or not a Teac 2340
reel-to-reel uses a crystal oscillator for the capstan motor, or the
60-cycle power line. Anybody got that page from the service manual? Mark
Glinsky's page 404'd me when I tried it. If it's the power line I was
thinking of building a little sine wave inverter with:

a tuneable EXAR 2206
some IRF HEXFETs
a big 12v filament transmformer wired backwards

Pretty goofy, huh. I should have all these parts laying around. At least I
feel at home with you guys :)

Best Regards,

- Gene
