For anyone who is interested, here are some pictures of the guts of my Boogie Rectoverb: Photobucket
I have a question about where the bias resistor is located on this amp. I read on some site that this one person's Boogie had a 22k bias resistor. Looking around, all the resistors had 5 bars - 4 colored and a tolerance bar. What's that all about? There are also those 2 ubiquitous (sp?) looking things (they might be resistors) on the PCB below the power tubes. Would those be the bias resistors? I only took shots around the filter caps because that's where the bias resistor was with the aforementioned person's Boogie. My plan is to install a potentiometer and resistor in series so that I can bias this amp properly. I'm still waiting for those parts to come in, but in the mean time what am I supposed to remove?
Many thanks,
Eric
