A 1962 Brownface is listed for sale on Bananas at Large's website.

Excellent Condition. Overhauled by Chris Barnett. No Slip Cover.

Serial 55938 makes it mid-year 1962 which is 6G12-A circuit. Label is partially missing though stamped first figure is "L" for 1962.

Original Oxford speakers in good working order. No rubbing, no tears, stiff cones. Dated (3) 465-236 and (1) 465-233. All: 10K5-XG748 plus all cones stamped original P4630.

Original transformers: PWR 606235 CHK 126C1A 606241 OUT: 125A9A

Original tolex and grill cloth in terrific condition as shown.

Tubes: New pair Sovtek 5881 12AX7s mix of GE, Tung-sol and Chinese.

Complete electronic service including: Many resistors replaced as needed with metal film. In the B+ drops metal film resistors are quieter than the original carbon resistors.

All signal path capacitors, coupling and tone, are original.

You want the amp to sound right.

All filter capacitors replaced. high plate and screen voltage so plate and screen capacitors have 700v capacitor rating for surge protection, reliability and long life: this also contributes to the amplifiers punchy robust tone. Originally Fender specified 600v capacitors, but normally used.

Cathode and bias electrolytic capacitors replaced.

Fender first made the Concert in 1960 as a 6G12 circuit with a five tube preamp with two tubes dedicated to the vibrato circuit. Fender then refined the circuit as 6G12-A which has the full tube preamp complement with the three tube vibrato. The three tube is unquestionably the best vibrato Fender ever produced and this amplifier is a particularly fine example with rich, deep vibrato.

Overhauled by Chris Barnett: Replaced both volume potentiometers, 2-OEM Fender 1meg audio pots, Checked for leaky capacitors.

Mentioned in this March 1978 Guitar Player interview.

Then I got into a tweed Fender Bassman, and recently I got a Fender Concert, which is an old brown one, from around 1959, with four 10” speakers. I use a Hawk booster through that just to roughen it up a bit, or if it's a quiet number I plug straight in and keep the guitar clean sounding.
