+1 very rough. That outline on the mains trannie looks strange.

I think that both trannies are original, it is the modded/drilled front panel that stands out. Inside the bypass cap on the mixer is a styrene and the tone cap is a whopping 0.022uF (22,000pF!!!) when it should be 256pF. Interesting to see the 47pF cap across the NFB resistor. I have seen NFB bypass caps (usually flat silver micas) on some early JTMs and wondered if they were stock although I have not seen one on a schematic.

His 68 Superlead looks interesting http://www.ebay.co.uk/itm/marshall-plexi-jmp-super-lead-amp-100w-all-original-1968-perfectly-working-head-/190876207940?pt=FR_YO_InstrumentsMusique_Amplis&hash=item2c711bcb44 but this has a new cap board and has modern cathode bypass caps and a few other odds.

Both amps are definitely players grade and advertised as such (and with prices to match) I would have no issues.

I was thinking I would like to see a shot with the JTM45 removed to see more of what appears to be a pretty nice residential area.

That's why I play the lotto!
How can you tell the difference between a chemist and a plumber? Ask them to pronounce 'unionized'.
