Fender ceased production of 5B6 Bassman amplifiers during the spring of The 5D6 was a major departure from the earlier 5B6 Fender Bassman model.

Teaming the pre-CBS Fender Stratocaster and the late s tweed Fender Bassman amplifier has been a dream for most every guitarist at least once in their playing career, and more stars have used this combination of gear – or something extremely similar – to make memorable music than perhaps any other coupling of guitar and amp. From right to left, they implement a first-stage preamp, a second-stage voltage amplifier and DC-coupled cathode follower, a long-tailed-pair phase inverter, a fixed-bias push-pull power amp, and a high-voltage DC power supply.

Fri, Dec 30, Mon, Jul 06, Good tubes but not as valuable as the Brown base. I would be putting these in my Cameron modded Marshall Aldrich. Any idea how they compare to SED winged C? For new production imo the Winged C’s are my overall favorite. For guitar my first choice is the Mullard XF2 single getters, not the double which are great for hifi but too hifi for guitar. My second choice is close between the old Tesla brown base and the Amperex.
The black base Teslas I had were also very good. I would take any of these over the Winged C first. The german made RFT are also good tubes at lower plate voltages. I found them to fall apart somewhat under heavy power and volume. Its hard to find a seller who knows how to match them.
