Build Reports / Re: Collosalus 24 Build

The pinout in the 5532 is the same, but they're not the same thing. That's your LFO section which would make sense why the regen pot is t doing anything. Have you gotten the replacement chip yet?

First test, I'll take all IC out and test b+ voltage to verify that this is all correct.
Then I'll put IC in and test all voltages again.
If off then go through and test all resistors.

A bit late, but...THANK YOU for keeping me alive Brian, and all here.  Jimi, hope your wife is recovered!

Dude please. You kept yourself alive. The community just helped a little to keep the lights on while you recovered. As many of us would do for anyone who is NotAGeek.

But, I will say: no more 8-Balls for you at the dance hall on Saturday nights.

Hi Jeff, thank you. She did. She's been in the hospital a couple of more times since. Today she is doing well. I hope you are too.

ok here is a pic, not that it shows much as ive been over and over pcb with a magnifing glass!!
rebuilding the 2015 version as well now as it did actually sound ok even though it had the wrong trimmer in it!!
the made up resistors i measured before i put them in and they were the correct resistance, most were the 30k ones, which i used 2 x 15k.
the only different values ive used is c30 and c27 are 470uf, i cant see c27 being a problem but maybe c30 is an issue?
c2 is 47pf, c23 is 30pf and ive used 15uf tantalums in c20 and c21. IC5 is a 5532.
3 of the caps i made up with two caps to get to the correct capacitance, these are C1 = 33nf and c4 = 33nf and c5 = 3.3nf.

General Questions / The Imp 1590A PCB?

Last post by davio - June 27, 2025, 03:08:14 AM

Recently got the urge to do a Klone build and would LOVE to pull it off in a 1590A enclosure. I know MB put this out 5 years ago but was wondering if there's any way to beg, borrow, steal, or (more likely) buy a PCB for it? Would love to skip trying to design the layout myself and ordering a custom job online. Is it still available anywhere or am I SOL and need to sit back down and dust off my KiCad chops?

I'm a sucker for old Ibanez stuff! Will have to watch for this to come back in stock. Love your build!

Pics would be huge. Otherwise, we'll just be guessing all day.
