Motorola RF Millivolt Meter

 This is a Motorola S1339A RF Millivolt Meter I got from a friend. It was a piece of gear that his late dad had, and was packed away in a barn. It's actually a Boonton 92E that they rebadged for Motorola. This is an excellent RF millivolt meter. It had years of dust/dirt from the barn, and even had a large mud dobber nest inside. I cleaned it up and found it was partially disassembled, perhaps being repaired when it was parked. I repaired an issue with a socket for an op-amp chip, found fasteners to reassemble it, and calibrated it. The cases got a shot of paint, and it works like new. It's a great piece of test gear!

D&A Maverick Repairs

 This is a D&A Maverick RF amp. These are easily tapped for 40-10 meters monoband, later models had band switching. The PA runs pretty much like a Dentron GLA-1000 or the Amp Supply LA-1000. The 6KV6A driver section allows operation with lower powered rigs in the 5-25 watt range. The driver section can be bypassed for use with conventional 100w output rigs. 

This unit had lots of problems, and may have been a parts unit. It was missing the tuned input, missing the driver cathode choke, the PA load control was shorted to ground, was missing the input coupling cap, PA tank was broken loose from the tune cap, had bad caps in the rf sensing circuit, wiring issues, and cooling fan issues. All this was repaired, and she's running like new.

Realistic STA-20 Repairs

 This is a vintage Realistic STA-20 from around 1975. It was screaming AC hum loudly. It got a cleanup, a coat of clear  urethane on the wooden cabinet, new diodes in the power supply, new filter caps, all switches and controls were cleaned, and alignment. Plays and looks like new. Not bad for  50 year old tech!

Regency Polaris MT-5500 Repairs

 This is another Regency MT-5500 Marine Radio I picked up. No mic, no power cord, and a broken squelch control. I pulled the front panel and replaced the squelch pot, wired a mic to it, fabbed a power cord, and gave it an alignment. Works great, another marine radio ready for a boat!

Ten-Tec 229 Antenna Tuner Repairs

 This is a Ten-Tec 229 HF  antenna tuner I repaired for a friend. It's very clean and only needed a few things. First, it needed the dial pointer to be restrung. These have a fairly complex dial string configuration that takes a bit of patience. The sliding dial pointer had a pivot point broken, as well as a broken pointer. I was able to remove threads (to not wear / fray the dial string as it slides around it) from a machine screw and use it as a pivot. The owner supplied a generic pointer I was able to use part of to repair the OEM sliding pointer. After that was finished, it was upfitted with LED lighting. Nice tuner!!
