Re: LA500A opto comp MAY 2021 BUILD THREAD 500/51X
Actually - I am getting 2 x 20k measurements on the front lugs so maybe pot is fine after all? But can’t understand where issue would be on PCB. Perhaps it’s easier and quicker to get a new pot PCB at this point.

Re: LA500A opto comp MAY 2021 BUILD THREAD 500/51X
Ok so there still appears to be a short - in addition to this I had to cut a couple legs to get it out so not exactly workable. My desoldering is getting better but this was a tricky one

Re: LA500A opto comp MAY 2021 BUILD THREAD 500/51X
Worth if you have any pot cleaner to give the inside of the pot a tiny spray and remeasure with pot fully CCW to see if it returns to 10k. Otherwise the pot will need to be removed from the pcb and replaced. Okay so terribly slow with this over new year but I sourced some pot cleaner and the proble...

Yep just desoldered meter so it’s all good. Hope this helps. Worth if you have any pot cleaner to give the inside of the pot a tiny spray and remeasure with pot fully CCW to see if it returns to 10k.

Re: LA500A opto comp MAY 2021 BUILD THREAD 500/51X
If it is assembled remove the BIO take a good couple of photos of the top of the sc pcb and bottom of pot pcb first and I will check it Here we go! I did try reflowing make up pot joints just in case but it didn’t help. If you measure the makeup pot outside pads with pot fully CCW and BIO unplugged...

Re: Regurgitator kit Build Thread
Yes brilliant as I suspected thank you. A dumb question - would you supply all components necessary to populate a double/quad board - the price doesn’t seem to change between single and quad so a bit confused.

Re: Regurgitator kit Build Thread
Hi - I just would like to check if this kit is appropriate for bringing re301 space echo output (2.5k output impedance) directly into patchbay/interface using approx 18db of gain. Looks like it but I’m slightly confused as there’s a quite a few things available like the dingo/dingo pup and I’m not c...

Re: LA500A opto comp MAY 2021 BUILD THREAD 500/51X
Hi Joe - correct.
Can confirm the unit stays at unity gain with bypass wire in/out so the problem must not be on BIO PCB.
all the best!
