    What a great thread. I remember Ampeg was all the rage for a while growing up in New York City. My Father used to fix them for all the time in the mid 60's. When I was 16 I decided I needed a bigger...

    It turns out that Mark at OldRadioParts.net has a flat phenolic version of this plug for the princely sum of $2.00 each. So I'm taking the lazy way out & ordering a few for this project. Check out...

    Tom,
    You are right about the speaker wires. Each one has a short orange wire going to ground via a terminal strip. So no need for insulation washers. The more I look at it the easiest thing to do...

    I agree that Cliff jacks are better but I've got a bag full of switchcraft plugs & jacks so why not use them. I also thought of hardwiring the speakers.

    Thanks Enzo. These look about right. I'll check with them further or else go to plan B & use 1/4" jacks & plugs since I have lots of 1/4" plugs, jacks & insulator washers.

    Thanks Juan, I will use switchcraft jacks with insulating washers to replace the current connectors.

    The grey molded plug was made by Switchcraft. This one was drilled into & loose wires soldered to the pins. So far I can't find any old Switchcraft info to further identify the connector or cable.

    Juan, The schematic you looked at is a later version of the amp where the preamp & power amp are built into one unit. In this version they are seperate with two of those plugs used to connect each...

    No she was told that the warranty applied only to items we actually serviced. Got mad & left in a huff.

    An older thread by Wes on 04-04-2013 discussed this problem & what I hope is the solution, which pointed me in the direction of C40 & the CA3046. My question is what type of capacitor is C40. The...

    Hi Rob,
    Thanks, I never thought about the diodes as raising the peak inverse plate voltage, just as a means of making current 5AR4's last longer. At this point I'm leaving the Sovtek 5AR4 in since...

    All's well that ends well. 465V on the plates with a Sovtek 5AR4. The 66 Pro Reverb measures 462V. Sounds good, the 5V4 will most likely go into my old Gretsch 6156 Playboy instead of the 5Y3. But...
