Re: Need a second set of more experienced eyes on ‘71 super lead

Yes sir.

Red goes to the board where the death cap was and the common (orange) is on the bottom buss wire running through the polarity switch.

Re: Need a second set of more experienced eyes on ‘71 super lead

Found the nick in the wire and put some shrink tube around it and everything is back within speck. The pilot light was burned out so I got a replacement but it’s a 110-120 volt one. How in the world do I hook this up? I wired per the directions in the metro forum: solder red wire to bottom buss wire...

Re: Need a second set of more experienced eyes on ‘71 super lead

Yes, I meant to say VDC. Yesterday, I checked the grid leak resistors, grid stop resistors, coupling caps and they all checked out fine. I then measured the legs of 220k’s and noticed the leg of the 220k on the green wire side had no VDC. Lifted the board about a 1/2 inch and all tubes showed -50 VD...

Re: Need a second set of more experienced eyes on ‘71 super lead

Removed them and I’m back up to 500 volts pins 3 and 4 V4-V7 but I have no negative VAC on pin 5 on V4 and V5 :( V6 and V7 are both showing -39.8 I have an old quad of EL34’s on my work bench and just as I figured V4 and V5 red plated like a boss while V6 and V7 were fine. I double checked and the g...

Re: Need a second set of more experienced eyes on ‘71 super lead

Snip those silver 'Hunts' caps and discard for a kick off. Don’t you have to have the snubbers? They're actually across the AC input to the recifier and just cause bother more often than not. It's the first thing Marshall Service would do if they had it in. They are simply not required. If you want...

Re: Need a second set of more experienced eyes on ‘71 super lead

Consider them removed then. I thought they we snubbers. Still learning

Need a second set of more experienced eyes on ‘71 super lead

Guys, My buddy bought a ‘71 1959 that needs some TLC and I’m trying to help him with it. The amp hasn’t been modded but someone has definitely been in here at some point. I’ve replaced some resistors on the board in order to go from 6550’s to EL34’s, changed the NFB tap and resistor and removed the ...

Reverb reset?

I used the search function and couldn’t come up with anything but is there a reset procedure for the reverb? I hardly ever use it but it aggravates me that it only seems to work at random.

2466 transformer locations

If you are looking at the back of the amp is the power or output trans closest to the V1 pre amp tube?

Re: 2466 vs JTM1

Thanks for the replies guys. I really appreciate it. As I said previously, I use my 2466 in LD with Steve’s recommended JTM settings. Anyone else have good classic rock settings using Gibson’s? Think Aerosmith, Lynyrd Skynyrd etc. I can see a Hiwatt in my very near future since I’m more then happy w...

Re: 2466 vs JTM1

Thank you and thanks for the reply! Yes, I play at home but Volume isn’t a big issue for me as I live out in the country. I agree that the 2466 has a very usable MV. It’s a great amp and frankly I don’t see why so many people bash it. Honestly, I like the retro look of the JTM1 offest limited editio...

2466 vs JTM1

Long time listener, first time caller. I’ve recently came across on the offset JTM1 mini stacks at a good price. I don’t buy amps to collect, I buy them to play and the more I listen to YouTube clips the more I’m unsure of what the JTM1 will give me if anything over the 2466. I keep the 2466 in LD a...
