Does anyone have the full schematic for the jmf Spectra 180A solid state.. The chorus and reverb are not working. Thank you.

Hello WhyDidIBuy,
That schematic is available on 'Elektrotanya.com under Spectra 180A'. -
Oh, it looks like that is only the power amp/power supply section of the amp...

Although it is not labeled as a 180 preamp schematic, this is probably what you have. If not, it will probably be very close.
JMF Spectra used a lot of "common/modular" PC boards like Kustom and others. It is a bit hard to read, but better than nothing.

Thank you. I have a chorus reverb problem. Footswitch works but it doesn't turn off reverb or engage chorus. Any suggestions?Comment
