old Lindell guitar amp - no info on web - tube id - ?'s

68.163.99.110

I found a neat old Lindell guitar amp (I'd post a pic but my camera is down). It is a Model N 100 X. I haven't been able to find anything about it on the web or in the various schematic indexes.

The tubes light up but no sound, not even a buzz. One of the wax and paper capacitors is blown apart, can't read the values, but there is another capacitor that looks the same and it is marked ".01mfd +-20% 600 W.V.D.C. Dumont 157." It doesn't have a line around one end or a + marking.

- is this an electrolytic?
- does this cap being blown up point to a likely suspect?

The rectifier tube is a 12AU6, then there are two other tubes, one is marked 50C5, the other is indecipherable, but looks to be similar in construction, except it has a clear top.

- Any idea what tubes these are? Likely replacements?

I already tried putting an electrolytic with the same values in place of the blown cap, with no change (I tried installing it in both directions). Next steps?
