Hi all, First off, sorry. I don't have a schematic for this amp, just a layout. Looked around but could not find one; would have rather used a schematic to be honest. Anyway when I started putting it together I noticed a 220K resistor between the diode rectifier and first filter cap, attached to the standby switch (I built it without the switch). I'd never seen such a large resistor in that spot and thought initially it would kill the B+ voltage. Well that's what happened. Fired up for the first time today and I was only getting max 75VDC at the first filter cap before it started settling down lower. So I pulled the resistor and hooked the rectifier DC out directly to the first filter cap. Now the amp's getting the DC it should, low 300volts, and sounds killer. Anyway I'm wondering if anyone tell me why that resistor would be there? Thanks!
