I just picked up this used London Pro today and I'm looking to retube it. I pulled out the existing ones and I'm not convinced they were in the proper spots. The 65Amps website seems to be down so no help there. From what I can gather, it's supposed to come with 2 x EL84, 2 x 12AX7, 1 x EF86, and 1 x 6CA4. Here's what I pulled out and the positions they were in... According to the only image I could find on the net, this doesn't match up. From - https://www.premierguitar.com/articles/65amps_London_Pro_Amp_Review For you amp geniuses, here's what the guts look like... (I tried up loading a larger version but it keeps shrinking it down. If you need a bigger one, PM me.) The sockets in the last photo line up with the sockets in the other 2. The controls from left to right are; - Volume for the EF86 channel with pull boost - Tone for the EF86 channel with pull bright - Mini-toggle to select channels - Volume for the 12AX7 channel - Tone for the 12AX7 channel - Master volume/voltage (shaft only since knob is missing) - Standby, power light, power switch Thanks in advance.
