QR Code Link to This Post
The amp does have minor scratches and dings consistent with normal use, but all corners are solid and the casters are in good working order.
Recently serviced (per shop where I bought it from). The original circuit was designed around a 115V power transformer, which causes the power tubes to run hot at current 120V line voltage. The service work added an extra filtering stage and resistor to reduce hum and lower operating voltage for the power tubes, and increased the cathode resistor from 125 to 150 ohms to bring bias current to the optimum value. The result is an amp that runs cooler, quieter, and more reliable than stock.
- Power tubes: 2x EL34.
- Preamp tubes: 4x 12AX7.
- Speakers: Original 2x Celestion Vintage 30.
- Controls: Volume (with pull boost), Treble, Mid, Bass, Master Volume and Reverb.
