Solid-state Pultec EQP-1A pictures?
« on: October 15, 2018, 06:38:47 PM »
Hi all,

Am trying to build a pair of solid-state Pultecs and am interested in looking at the insides of vintage units. Researching online, I could find TONS of tube Pultec pictures (insides and outsides) but NO inside (or for that matter, rear) pictures of the solid-state Pultec...

Can someone throw me a bone and provide some links or even some pictures in this thread? Would be most appreciative!

Thanks,
Chris

Thank you!!  ;D

If anyone else has other photos (e.g., inner rear panel, inner front panel, etc.), please share if you have them. Very much appreciated!  ;D

Best,
Chris

This is better, thank you. Need a few more if anyone's got them, slightly different angles, etc. FWIW, I'm trying to build a clone, including down to the AC/DC +/-15 VDC subminiature power supply module like the originals, powering the 2520.

Need a few more
the radial lead capacitors are obviously not original nor warranted.
a sharp eye will notice one is backwards.

?? They're both negative to ground, isn't that what it should be?

Looking at the schematic for a 312:



it looks like the lower cap in that pic (i.e., "C2") should be flipped around with negative terminal going to white wire (V-)? No?

Also, more pics, please?  :-* Other angles of 2520 and terminal strips? :)
