No, you're right, there are no indications that a logo was ever on the front of the amp. Do you know when they started covering the amp in Tolex? In looking at the Rick site, they have old catalogs, but not one that includes my specific amp. There's a hole where the catalogs jump from 1936 to 1953 ...

Thanks for responding. I did get the speaker fixed, and it sounds great now. Yes, I plan on having it looked over by a tech soon. So, is my amp just missing the Rick logo, or did it come this way originally? Don't really see evidence of it having been there, but maybe it was removed long ago....

Really?? I've never heard that. Interesting. I wonder if that applies even when moving to different climates. In the last year, I moved from a relatively damp environment to a pretty dry one.

One thing that no one's mentioned is whether to loosen the strings when a guitar is stored and not played for a length of time. I like to loosen them to keep the neck from having tension on it all the time, since I don't have a climate-controlled storage area! Opinions?

Wow, that is so informative and helpful! Thanks a million!!!

Regarding your comment on the phase inverter tube, this amp has no trouble at all making beautifully clean tones, so I guess I got lucky!

I think the amp had been serviced, somewhat sloppily, in the past. I'll look again more closely ...

Thanks for all the info. Here are the tubes for the amp as hand-written on the chassis:
5V3 (has a GT 5Y3 - does this overdrive sooner?), 6V6, 6V6, 6SC7, 6SC7 (all RCA's)

What's the easiest way to know if it is a fixed or cathode bias? Here's a link to a schematic from the Rickenbacker site ...

Thanks for the advice, Greg.

As I know nothing about tubes, here comes a dumb question: I don't replace it w/ a 6V6? Which of those that you mention would help to break up into overdrive easier (if any)?

And, will the amp require biasing when I do change it?

EDIT: one more question. In ...

Some photos of the little bugger. It's definitely seen some use....

Here is the speaker in question.

Original? Worth re-coning?

I recently got an early 50's Rick M-11 amp. There is a high pitched ringing when the volume is in the middle ranges, and the ring goes away at volume levels of around 9 and above.

Lightly pressing on the 2nd 6V6 tube (RCA) changes and slightly mellows out the ringing. It looks as if the tube ...

Also, what is the rating on a speaker for this amp. 8 ohms?

So now I'm a proud Rick owner! I hope to post pictures soon. But I wonder how I can find out the date of the amp. I don't really see any serial numbers, except on the speaker (4651433).

It calls for tubes in this config (handwritten on the chassis):
5V3 (has a GT 5Y3 - does this overdrive sooner ...
