Vintage Heathkit Ua-1 Monoblock Tube Amplifier Transformers Tested Good

Here is a vintage 1958 Heathkit UA-1 EL84 tube amplifier ready for a nice restoration. I ran a sweep on the output transformer using a signal generator and a scope. I also connected power to the power transformer and checked output voltages. I will guarantee both transformers are good. However, this needs a full electrical restoration before being put into operation.

I would recommend that ALL of the resistors and caps be replaced (there aren't that many). I have cut the power cord off of this to prevent anyone from just putting in tubes and plugging it in to see how it sounds. That would be a great way to destroy one or both of the transformers. Of course, he immediately filled it with tubes and plugged it in, then sent me a message that it sounded terrible.

You'll want to get some nice new production or NOS tubes to go in this after it's serviced, then it should be ready for the next 60 years. These are beautiful sounding amps with efficient speakers.

The paint on this is fair to good. It would serve nicely as it is, or you could have it repainted while it's torn apart for restoration. The feet on the bottom are worn out. Includes the preamp input shorting plug.
