1974 Fender Twin Reverb Vintage Silverface Tube Guitar Amp Head Conversion, 40 Watt


+ shipping

Out Of Stock
Up for sale, a 1974 Fender Twin Reverb, converted to a head and modified to run a pair of 6L6 power tubes and a GZ34 rectifier. Delivering a tonal response that splits the difference between a Super Reverb and a Pro Reverb, this "Twin" offers rich, glassy clean tones without the sterility often associated with Silverface Twins. Converted to earlier Fender Black Panel specifications (save for the Master Volume, which is still in the circuit), this amp is warm and smooth, with overdriven grit as you turn it up and sweet tube rectifier sag, pushing roughly 40 watts. A rotary ohm selector has also been added to the head, offering functionality at 4, 8, and 16 ohms.

The preamp remains largely original, with only one new pot and a few smaller caps substituted as needed to ensure optimal performance. The majority of the original blue signal caps are intact, along with the CTS pots that have visible date codes from the 15th week of '74. The power and output transformer have been substituted with transformers from Classic Tone, smaller than the Twin transformers and in-line with the amp's new 40 watt output. The original reverb transformer and choke have been retained, both dating to 1973. The power supply has been fully recapped with Sprague Atoms, and the amp features a three-prong power cable. The tube set comprises a pair of properly biased Sovtek 6L6GC power tubes, a Sovtek 5AR4 rectifier, and mostly modern valves in the preamp from JJ.

The chassis has a clean original faceplate and full complement of vintage witch hat knobs. The head cabinet itself is modern, well constructed and featuring smooth black tolex and silver sparkle grillcloth. The hardware is all modern as well, save for a vintage Fender logo, with new nickel handle caps and chassis straps.
