I'm copying this over basically from my post on the Gretsch pages. I realize that an old Gretsch amp might not be very well known around these parts, but here's hoping, right? Anyways, here goes: I bought this Gretsch amp from here a few weeks ago and it arrived today. From as far as I can tell, it's a Gretsch Electromatic Twin amp from 1954 (serial number X33747). However, I simply cannot find any information about this model ever existing online. The closest thing I've found is an ad from 1955 for the Electromatic Twin, and it's basically identical. Only problem is, mine has no tremolo at all, whereas the 55 does. So what in the heck is this!? I'll be doing a full restoration at some point - she powers up now and you plug in a guitar and it's audible, but you need to turn the volume all the way up to work well at all. I'm hoping new tubes, plus some new wiring will fix that. We'll see! First thing on the docket is to completely clean the tolex. Thanks guys! Hope somebody knows this. Here's the 1955 ad: And here are pics of the amp the seller sent me, sized down to fit on the page: Details: The amp has 5 tubes. A 6SQ7 and 6SC7 in what I assume to be the preamp section, a 5Y3GT rectifier, and 2 6V6GT power tubes. The 6SQ7 is the only one I'm intrigued by, as it seems to be in fine shape, but when I took it out, there's this weird bell like rattle in it. Not so much like something's loose inside (although that's more than probably it), but it sounds like a bell ringing when you shake it. Weird. Lastly, there's this Mallory can, which I presumed to be a cap. It says "Mallory Type FP" on it, so I googled that. From what I'm reading it's a cap of some sort. And if that's the case, I'm not going to be touching it until I know for certain what it is (I know about the dangers of old caps, and caps with a charge still in them). While it's more than likely nothing to worry about, I'm not taking my chances. Anyone know anything about them? Here's a picture I just hastily took: Lastly, for anyone curious, here's what the guts look like. Surely not the prettiest wiring job ever done, but I don't see a PCB board so I'm not complaining.
