Awesome congrats! If it sounds good leave it as is and rock it! Welcome to the forum!I’m a long time lurker, I’m not sure if I’ve ever posted. I picked this up today for around $1600 US(I’m in Canada). I know it has a master volume added, and the switches aren’t original… Any other major components look non-original? It sounds amazing View attachment 98705 View attachment 98704 View attachment 98705 View attachment 98706 View attachment 98704 View attachment 98705 View attachment 98706 View attachment 98704 View attachment 98705 View attachment 98706 View attachment 98704 View attachment 98704 View attachment 98705 View attachment 98706 Thank you in advance.
Eyes of a hawk!Quick summary:
One of the output tube sockets replaced (white ceramic are stock, brown phenolic not)
All screen resistors replaced (originally 5w Welwyn’s)
PPIMV and bits of course
Replaced bias feed resistor
Switches you mentioned
Pilot lamp replaced with new Marshall type
V1b 0.68uF 160v mustard replaced.
Output selector replaced (maybe why OT wiring untidy - or could be replaced OT although fixings look original.
Main thing is that it sounds good. Most road warriors do, there is a reason why closet queens don’t get out much!!
I mentioned the OT not only for the odd wiring, but for the fact these transformers weren't through bolted on the corners of the cores, simply centre bolted.
I have been obsessing about old Super Leads and using the search function to look at old posts and pics of Super Leads. I came across this 1972(like mine) that also has a 4 bolt OT. Would you say this OT is a replacement as well? Or could it be a component they used briefly in 72?Now that I am home and on my Mac I can see what you mean (and the dye mark on the centre hole where the original bolt went) so yes, replaced OT too, but obviously a good one. I did work on a completely stock '67 Black Flag JTM100 Bass amp a few years ago with a Drake 1202-132 2" OT that came originally with x4 corner bolts as standard.
Thank you for your expertise. Just trying to read as much as I can and figure out all these mysteries. I’m very happy with the amp, just curiosity really.V1B cathode bypass cap (sozo) is not original. V1 socket is replaced. (Original would be riveted, no screws and nuts.)
Transformers look original except that the OT's end bells are held on in the corners, rather than the middle screws in the sides as was previously mentioned.
If that indicates a replaced OT, then at least the tech seems to have kept the original end bells and clamps. Why would he not use the original screws? Maybe this OT has a thicker lamination stack and the original hardware wasn't long enough. That's totally speculation.
Patina matches everything else. Looks just like in my '73 SL, when I got it.
It's pretty close to all original. You got a good deal if it runs right. At that price it'd be worth it even if it needed a transformer.
