This American classic has seen heavy use and sounds incredible. Its appearance stands as a testament to how reliably these amps hold up over the years, still offering rewarding use to their owners 67 years later. This is a special Bassman circuit, often referred to as the "two-hole" Bassman, as it features only 2 inputs instead of 4. If you notice the second rectifier tube, you might wonder if it resembles the Low-Powered Tweed Twin amps – and the answer is yes! If you compare the schematics, you'll see the similarities. Both share the same 7993 power transformer, with the Bassman using a 2-ohm version of the Triad 2818, known as the 2820.
The back panels likely went missing at some point and have been covered with replacements, that are a bit rustic to say the least. It's even been mounted with homemade casters, for the sake of easy travel. Internally, the power cord and electrolytic caps have been replaced, and a filament balancer pot has been installed. All of the Astron coupling caps have been swapped for older orange drops, which don't seem to diminish the sound in the least. Thankfully, all of the original carbon comp preamp resistors still remain. The speakers are probably not original, but they appear to be very old Oxford types, judging by the frames. Despite not having codes, these should date to the early '60s, making them period-appropriate while still delivering tremendous performance.
This is a great opportunity to acquire a high-performing and rare amplifier, priced 30% less than current 1959 5F6-A Bassmans and less than half of what you would pay for a Low-Powered Twin. If you don't mind the rustic looks, then be sure to grab this soon – an amp of this quality and value will not last long!
