Does the top of the chassis look like this? This is the 7TU12  The chassis, tuner and amp may be the same on that model as your coffee table set.

From what I can see this is a very basic unit. It has a EL84/6BQ5 tube per channel and those are right next to 2 small output transformers in your pictures. The speakers appear to be automotive type 6X9's or thereabouts. The large aluminum can mounted on top of the chassis is the electrolytics. There will be anywhere from 2-4 sections inside. There will be stamped markings on the side wit the Microfared and voltage ratings. Each section can be replaced by individual capacitors.
The non-electrolytic capacitors will be made out of cardboard tubes that have wax sealed foil inside, and ALL of those should be replaced. If they are ceramic disc those should be fine.
If you decide to go through with this then put a post on the electrical restoration section

Thanks. The client has just asked for replacement speakers for the moment, but they will probably want further work once they get it hooked up
So automotive 6x9s, but it looks like it needs a tweeter as well. Also passive crossovers, unless there is a crossover is in the amp.

Hmmm. Looks like automotive 6x9s usually come 2 or 3 ways these days, I guess that solves that problem. What impedence would you suggest?

I would really stress that simply sticking in a set of speakers and handing it back to the client will probably result in the old electrolytic capacitors failing either immediately or likely not too long after the user starts using it again. If that happens it will possibly damage the power transformer among others. If you don't have the technical ability to do this then either find someone that does or have us walk you through the process. Otherwise the thing will more or less be a ticking time bomb.

I have the technical ability. I will recommend it to the client. But I can't do work they don't approve an estimate on. Right now I'm just trying to do the research necessary to do an estimate, which is finding the right speakers, and finding the service info for the electronics.

This probably had low wattage high efficiency 3.2 ohm speakers, most new automotive speakers would be designed for an amp with hundreds of watts. Still may work well, though, hard to say. I believe I have some 6x9s from the tube era if you end up needing them.

Have you removed the tuner from the cabinet ? There should be a paper label (model number) pasted on the side of the chassis. Greg.
