Going nice and slow, especially if this is your first restoration, is good advice. Replace wires and parts one at a time so you don't lose track of where you are, and it should be fairly straight forward.

As far as capacitor values, don't worry too much about not finding "exact" replacement values. In other words, you'll run into some .05 uf caps; modern .047 uf will do the job. 33 uf will replace a 30 uf, 47 uf for 50 uf, .033 will replace .03, and so forth. The important thing is the working voltage - replace with either equal or greater value; don't go down!

After the caps are replaced, an alignment will help it operate much better. We'll cross that bridge when we get there. It sounds like it sort-of works right now, so odds are you have a good set of tubes.

One more bit of advice - replace the power cord with a modern polarized plug. Wire the neutral side (with the wide blade) closest to ground. Be sure to ask if you have any more questions - we're here to help! Icon_smile

Sounds like a nice radio - good luck with it!
