An old, original Orange PA120 here, on a PCB but still nevertheless a real good amp!

I sorted this one whilst the owner (Will) was here in the workshop. It made sense to do this as he had travelled about 120 miles for my services…..all the way from London.

If you look closely at the Mullard (Mustard) cap that I have replaced (approximately in the middle of the photo…..and about two-thirds to the right), paralleled to the 100k resistor. This is on one of the splitter anodes and was short…..hence no drive!

All original Mullard tubes…….what more can I say!
