I have a Frontman 65R on my bench that pops loudly for about 2 seconds when it is switched on and then works properly. I checked for DC on the output and there was none. Switched over to ac to see what was going on and there is about 45v on the output for about 2 seconds when the amp is turned on. It is after the preamp because I opened the pwr amp in circuit to see if the preamp was causing the problem. Any Ideas?
Thanks,
