The AIWA TP-1011 is the reel-to-reel tape preamp Richie Blackmore from Deep Purple used to drive his Marshall.  I’m not a huge Deep Purple fan, but I do like the sound of some of these old reel-to-reel preamps.  This layout is for the stock circuit running at 18v.  If I ever get around to breadboarding the mods I tried in LTspice, I’ll post another layout.   

Here’s the discussion on FSB, including a verified layout with a trimmer to control the first gain stage.

AIWA TP-1011 REEL TO REEL PREAMP – VERO LAYOUT

Build notes (comments below from ConvergentSound);

SCHEMATIC AND POTENTIAL MODS

Reduce down from 18v to 9v.  18v had mountains of output level on tap – I can see how stories of Blackmore cooking amps could be true.

• Reduce coupling cap size to roll off some low frequencies   
• Very flat response with the stock circuit
• Aiming for clean boost all the way to fuzz
• Try NPN germanium for Q3   
• Trimmer to control gain of the first stage (as per FSB thread)

   

NOTE:  images below are from the modded circuit running at 9 volts.   The original will distort quite quickly, which seems to be normal.  Basically to the point of fuzz.
