Thanks for the diagram!

I posted pics in the other thread of the two, they are a little different.

I'll try to start testing it today.

Got the pics on other thread, wondering what your test results were?

Been out of town. Hope to test it tomorrow evening

I tested across all the coils and found continuity across all.

I think I am just gonna hook it up and see what happens!

I did notice that the voltage selector in my amp is gone, so I don't think I am going to hook anything else up except 110v.

Okay, I got it installed and what I think is the correct wiring.

On initial power up every thing seems okay, light comes on and no burning or smoking. PT is cold.

When I turn the amp from standby to play, it works like it used to. The only thing I notice is that all 4 power tubes seem really red and hot. The PT got a little warm but again no smoke or smell. I only let it go for a minute or two and shut it off. It did seem to keep playing after switched to standby. I don't recall it doing that before.

Is it possible i wired something wrong to make tubes seem so hot, or is that normal? I didn't re-bias either.

As you can see for pics, the wires were not exactly same from each transformer. I used the T2562 schematic to try and matchup best I could.

Any help would be great!

Thanks

Changing the PT can (most likely will) change voltages and bias point. I would definitely check voltages and set the bias.

Okay, where do I begin on voltage checking?

Hopefully Toner is right and all you need is a rebias, but I did suggest that you check all the votages out before you hook up!

Sounds like the PT is a runner anyway.

You must check your bias setting and the rest of the voltages in the amp before you proceed further.
