Janus Power Amp rebuild FAIL

[Yaniv Brener]

Hi everyone. This is not the message I wanted to write, but here we are. I was re-capping the Janus power amp using the Vintage Vibe kit, and accidentally soldered Q2, Q4, and Q5 the wrong way. I reconnected the Molex connectors & turned it on; there was an ugly hum, a puff of smoke, and now...silence. What did I burn, and how do I fix it?

Figure out what burned up. Replace those things. Then power only the power supply, no amps, and verify operating voltages, before reconnecting either amp.

To prevent damaging speakers, attach 16 ohm 100w dummy loads to the speaker jacks when testing the amp channels. Dim bulb tester is also essential when doing a "smoke test" to prevent future smoke.
