This is an Alamo Montclair Reverb, model 2565. Based on the codes on the transformers and pots, it dates to 1976. It is a hybrid design, combining a transistor preamp to a tube phase inverter and cathode-biased 6V6 pair. I can already hear some people groaning about the solid state preamp, but put your pessimism aside… this amp has a great tone. Of course, I’m sure it doesn’t hurt that it is running some beautiful old Sylvania tubes that are still going strong.
The Alamo came into the shop in need of caps and a 3-wire cord, and the tremolo wasn’t working. I replaced all the filter caps with F&T, and used Sprague for the low voltage electrolytics. The tremolo problem turned out to be just a faulty pot, which got replaced with a CTS. And, of course, I cleaned all the pots, jacks, and tube sockets.
So, as I said, this amp has a nice tone to it. Full and clear, with just a bit of bite. The reverb won’t wash you into surf territory, but it adds a lot of warmth and dimension. The real surprise of this amp is the tremolo, though. It has great shape to it, and can get really choppy without being noisy. Tons of fun! I can see this being a great recording amp, and I am sure my customer will get a lot of enjoyment out of it.
