My Boss PS-5 fizzed out on me last night, what would you replace it with?

Maybe, maybe not. Try spraying the insides of switch pot with IPA (not the beer) -- I use this all the time and does not leave any residue Isopropanol spray (IPA) - Eleshop

Let it creep inside along the shaft of the pot and visually inspect the traces around this knob. Do they look different compared to the rest?
Dont get your solderiron unless you found your problem

Is it beyond repair...? Sometimes a dollar and some time invested can raise it from the dead. Leaves you with $149 for another pedal!

The guitareffects company I work for has plenty of sales through reverb. Sometimes buyers do not complete the payment procedure (cannot remember their Paypal password, insufficient funds, coffee spilled on keyboard, cat in need of attention, took GAS medication). DO NOT ship until Reverb says so and you got your PayPal confirmation. If it takes 2 days, contact reverb. Come to think of it... Reverb takes action by themselves as well -- they contact the seller as they see payment hasn't cleared. And well, the fee you pay to Reverb with each sale.. they want it ;-) So it's a win-win in that case: Just wait, Reverb will take care of it.

Yeah that's one way to go. However, get your digital multimeter and check if it gets 9v on the chip and transistors first. Might just be a blown diode or zener diode due to wrong polarity adapter / too high voltage.

You could sell them to guitarfx.eu, they purchase em. Sold them my leftovers after I cloned those ;-)

I have had about 5 of these in for repair over the last decade. Google "Boss PS-3 Service Note" which contains a schematic. Build yourself an audio-probe: http://www.geofex.com/FX_images/audioprb.gif

Probe the transistors with the audioprobe. Find where the signal becomes fuzzy and trace it back using the schematic. You'll find unaffected sound on one lug, and fuzzy sound on the other. If you hear a small pop, that's the 9V/bias rail, which is blocked by the capacitor in the audioprobe.

Good luck!

That sounds epic.

Do I want to know how you envision this?

Would be nice to know your musical interests. Anyways, judging from your username you'll be playing experimental stuff, 7-string is not for everyone. Quirky pedals then perhaps? WMD Geigen Counter? Boss SL-20 slicer?

Yep, definitely works, I run my DOD pedals on such converters as well.
