An addition Pat, when you have a 4 section filter cap, you run the risk of hum because there is a common ground, where the f/e needs to ground at the signal input.
Hi Pat, I'm new to your channel. Your Knowledge of these old is unbelievable. Have you started your own amplifier? If more companies had you fine tune their amps there would be a lot less frustrated musicians. Thank you for your willingness to share your vast knowledge!!!
Hey Pat, nice repair. I'm not sure if you are aware, but Gibson back in the day had many different companies building the amps for them. Now, Gibson, as you are aware, bought Mesa Boogie from Randy Smith, and I can imagine the changes from that buyout.
Those old multi can caps are available at www.tubesandmore.com/products/capacitors?filters=Brand=CE%20Manufacturing&sort=&page= They are using the original Mallory equipment to reproduce any values you can think of. Thanks for sharing your work.
