While it sure is no Heathkit, the old Dentron GLA1000 amplifiers were sold by the thousands. Providing upwards of 1200 watts PEP input, they used a set of four sweep tubes. The power supply inside the GLA's was always a bit light, and with the units hitting 25+ years old, it's time for a upgrade.

The voltages inside this amplifier can and will KILL YOU!

There's a lot of wires to be unsoldered and then reconnected to the new pcb assembly. If you're not up to the task, then you should find someone that can perform the work for you.

The GLA-1000R will come as a fully assembled PCB. The price is only $65 +$10 shipping

The GLA-1000R upgrade has the following features:

New high voltage capacitors with TWICE the rated capacitance of the old ones

New flame proof resistors rated at 3 watts instead of 2 watts.

Meter current shunt resistor now 5 watts instead of 1 watt

1N5408 3 amp at 1000 V diodes used

Glass PCB with plated though holes, double sided and with a solder mask on both sides. Both sides have a silk screen.
