Worth repairing?

[Sheggy]

I have an old Eagle SA-200 integrated stereo amp which is in need of an overhaul. It does work but will need a full set of tubes and re-capping.

Any advice would be greatly appreciated.

bump, bump.

I don't want to chuck it out. Sounded quite nice while it worked. I could make it my first tube project but I'm pretty sure it's a late '60s Japanese version of British tube Hi-Fi.

I'll get a picture up soon - see if that rings some bells.

Sounds like a good candidate for a first project.

I say rebuild it,and tweak it.
And,Welcome to the addiction!

Pictures would be really helpful. What tubes does it use?

There are six tubes in all, one I can't read. The others:

Ez81 - a rectifier I think, blew last time I tried to use the amp.

2x E8E/128x7

6D8D

8D8D/68Q8

mostly Matsushita

Those pics are kinda small... looks nice & clean thou. An upskirt picture.

the 1st tube in your list is likely ECC83/12AX7

and how many of each.

The EZ81/6CA4 is a rectifier. That it's blowing up is not good. Hopefully, the power trafo is intact and the problem is caused by old, dried out, electrolytic capacitors in the PSU.

I agree with Dave. It's highly likely you have a pair of ECC83/12AX7s in the unit. A reasonable use for them is in the phono section.

Matsushita made GOOD tubes. They acquired tooling from Mullard.

It's starting to look like the amp is some sort of single ended pentode design.

Please post photos of the tube labels, so we can do a better job of type identification. I'll venture a guess that you have either a pair of 6GW8/ECL86s or a pair of 6BM8/ECL82s as the O/P types. That would be consistent with 1 additional small signal type serving in both channels to provide gain that compensates for tone control losses.

If the "iron" is intact, the unit is worth fixing. The guys here can always work up a design that uses the platform well.

BTW, 6GW8s are scarce, but if you are willing to forego tone controls, EL84s should make satisfactory substitutes. 6BM8s are being produced in Russia and are not problematic.

If thats the rectifier next to the power transformer then it looks like "white death" has struck. No vacuum...
