Very cool player-grade amp with some interesting modifications and absolutely legendary tones. Serial number indicates 1974, with original transformers. Printed Circuit Board has been replaced; the amp is now hand-wired, point-to-point on an earlier, brown turret board with many of what might be its original parts in tact, as shown in the photographs. Caps, resistors, wiring, power cable, and other parts appear to have been replaced; pre-amp tube sockets may have been replaced as well. Various cosmetic dings and tears to the tolex, particularly on the corners, as shown. Mailbox letters BLHTX are stuck to the back plate. This amp received an incredible upgrade at some point in its life, someone(s) played the hell out of it, and it has been well maintained ever since. It sounds absolutely incredible.
