Might be the solution.
Thx.

Video looks great!

Ha!
I'd be asking for more than one PCB..

I was thinking more along the lines of some local stuff.

I've got nothing not built...

Maybe a 7inch single?  If you spin records..

Loaned mine out, just to give some variety; now she asked me to build one... in another 1590a!  Does anybody know of any pcbs on the market?

Take care of yourself,  man.
Get well soon.

Thanks for doing what you do Brian.
Whenever I get the hankering to build something MadBean is the first place I check in.

All the best in the new year.

Cool Beans!  Like the layout of the video.  Can't see where the tiny pots are clocked though when watching in a small window.

DC seems ok.  A bit low though on both circuits.  2.9 - 2.8V on most pins.  3.2V on pin4 of the metal film.  Bean's got his all up around 3.4 - 3.7V.
Haven't traced yet, but this could be it..
Hmm.  gotta 22ohm 1/2 watt in R5; the supply to the chip. All pins on the 4049 are on the low side of the pdf voltages..
I might have to change that to a 20 or so.. just tack something in parallel to bring it down some..

Might have to wait until tonight, got me some chores to do...

Voltages around the chips are pretty much the same,(and close to readings in the pdf) but carbon one is giving me too much fuzz, almost octave like on the decay.  (Almost fuzz factory like if you know what I mean).
I bypass the buffer and the tone still getting the same issue.  Something's going on around the 4049 I figure.. I don't think it would be the supply, probably one of the amplifier stages.. I think I'll see if I can signal trace through the stages.  All the resistors are carbon (these are older, I've had them since school) except R18.  Check and see if DC is blocked at C10 and C12..  Thinking of replacing the chip. 
Am I headed in the right direction?

been expecting that...  :P
