Reviews Summary for Dentron GLA-1000B Power Supply Upgrade Board
Dentron GLA-1000B Power Supply Upgrade Board Reviews: 1 Average rating: 5.0/5 MSRP: $The price is $59 plus $8 shippin
Description: The Dentron GLA amplifiers are just as popular now as they were in the late 70's. They run four sweep tubes and can produce about 1200 PEP input on sideband. On CW, you can see about 400ish watts, depending on the band and the quality of the sweep tubes.

Although the tubes are expensive, if properly tuned, they will last a long time.

The power supply, however, maybe the weak link. Nothing fancy, the original power supply is now over 30 years old. The capacitors have dried out, the other parts may have been stressed beyond a useful life.

This upgrade has it all. New double sided pcb with all new components. The diodes are over rated, 3 amps at 1000 vdc, and the capacitors have twice the amount of capacitance as the original ones.

The meter shunt is now 5 watts instead of the factory 1 watt unit.

I've placed glitch diodes to prevent meter damage.

The resistors are all flameproof and most are three watt units. Even the low voltage control circuit has improved components.

The upgrade comes assembled.

The instructions are thin, on purpose, as a novice shouldn't be inside this amplifier without proper knowledge. The voltages inside will kill.

This upgrade is for the GLA1000 B but should work in the "A" version as well. I have received a note or two that the voltage divider may not be the same in some of the "A" versions.
Product is in production.

Why just recap when you can "refresh"?  Time owned: 0 to 3 months
I found this product while just looking for capacitors to replace the ones in my Dentron GLA-1000B's failing power supply. The price wasn't too much more that buying the updated capacitors, and you get so much more for your money. I followed the instructions and recommendations that came with the kit, and my amplifier fired right up the first time subsequent to installation with full power available (previously was several hundred volts short). Great communication from Mr. Bryce was appreciated as well. Highly recommend!
