Old Amplifier Date/ID Help

[(MikeZito)]

To make a long story short - I bought this amp many years ago, and have been able to find NO information on it, (i.e. wattage, date/era, etc.).

This is an 'Encore' Duo. Looks like a 2x8, tube amp, with and on/off/bass knob, volume knob and 3 instrument inputs on the back. I can send larger photos if anyone thinks they can help.

Thanks.

What tubes (and how many of each) does it use, and can you post some photos of it's guts? That will help in getting you useful information. We'll want to see the transformers, and if you can, the underside of the chassis showing the components and wiring layout.

And, larger photos, too!

I may have answered one of the questions myself, by opening up the amp. To the best that my untrained eye can see, everything inside appears to be original. There are two old RCA glass tubes, both code dated to late 1956 - along with a few 'Dwarf Tiger Paper Condensers', which also appear to be from that same period . . . so, I am guessing that I am holding something from late 56/early 57. Unfortunately, there are no other tags/labels of any kind inside the amp. I have some inside photos - so, if anyone still wants to see the configurations, let me know and I will do my best of post some decent-sized images.

. . . . perhaps someday I will get up the courage to actually plug the thing in!

Thanks.

Don't plug it in! Better to make sure all is well, first.

YES! Old capacitors are prone to deterioration, especially in the power section. These may short when power is supplied and let all of the magic smoke out...

(laugh) Yes, that is why I have owned the amp for about 6 or 7 years, and have never used it as anything more than a $5.00 piece of vintage eye candy. One of these days I'll find a tech who can look it over, without charging me the price of a new Rickenbacker!

And boy, do they smoke... After they explode.

There are lots of amp techs around who could check that out for you. I know of one in the DC area who is really good, but there are others around too. Get on some amp forums and ask around and someone will turn up who will look at it for you and knows what they are doing.
