    Do you pay any attention to Capacitor ‘Life’ ratings?

    Closest I can find at Mouser for a 100u https://www.mouser.com/ProductDetail/KEMET/ESS107M016AC2KA In polymer caps, Kyocera RPF series and Rubycon PZJ are close at 8-9mm up to 470u but you gotta watch the lead spacing. Some are 2.5, others 3.5.

    Do you pay any attention to Capacitor ‘Life’ ratings?

    There are leaded solid Al caps. Same dimensions. Probably twice the price as there is likely a much smaller demand. Edit: see Nicilhicon PLV and PLX series Theyre both EOL though...

    I'll try my best but none of the below is warrantied 1) meh. Whatever works 2)see above. Maybe for more repeatable results. Maybe it was extra after the vref buffer? 3)little audible difference between them except maybe a little on bass. Use a 100-220n film. Done. 4)rule of 10x to prevent...

    3 circuits on one PCB

    I think you could use independent filtering just fine. As long as none of them are positive ground, you should be good. It's no different than Daisy chasing pedal power... Assuming you're making PCBs, I would isolate the grounds of each circuit and converge them in a star ground at DC input. If...

    Do you pay any attention to Capacitor ‘Life’ ratings?

    My bad. It was a 10v cap in a 9v pedal. Been a while. Peavey DSC-2 Was the only through hole component in the whole pedal. Reminds me, I need to check the other 2 in that series I picked up.

    Do you pay any attention to Capacitor ‘Life’ ratings?

    There are some pedals worth recapping. Some manufacturers used 18v rated caps for filtering on 18v pedals(cough, Peavey), while overbuilding every other aspect of the pedal. Ensuring service center business, I suppose?

    Do you pay any attention to Capacitor ‘Life’ ratings?

    You can derate the lifespan if you want. Biggest factor is operating temp. I try to buy 105C Al caps when able/cost effective. Always if being used in a power supply or enclosed with a power supply(like rack gear). The newer style solid Al caps have longer lifespans as well.

    I'd try a reset too I believe this is also the same between the 20 series, this from the DD20

    Nine ball OD

    Disconnect pin 6 of IC 3 from the circuit. Either clip the socket leg or bend the pin out of the socket. Bridge pins 6 and 7 with a resistance of 10k-470k. The in resistance of the opamp changes with volume pot so you'll have to experiment to see what works best. Or simulate it. I'm going to be...

    Madbean I think. Maybe Edit: BYOC had them... He also used a EHX microsynth I watched another 93 performance and didn't see any stomping
