Jay, et. El
The L4B seen in photos was shipped to AGL Electronics around 1973 to 1974.
Original owner was K5TM in Austin, TX
The amp was boxed and stored for about 30 years, that would have been around
1990
Tom moved to SC about 2017 and donated amp to local club.
W5AJ bought L4B with donation to club in 2017 and picked up at 2017 Austin
Summerfest and transported back to Midland.
At Midland, L4B remained in box and wife vacuumed around the PS until “The
Virus”
which said Virus (and Oil Bust) gave me generous amount of time to work old
projects!
The amp now sits in my shack.

Robert,
Nice work on a classic amp!
Could you give us some general history of your L4 B? Where was it had it been
kept?
The tank coil looks heavily oxidized, even flaking, from what I can tell.
Thanks far sharing!
Jay,

cleaning up L4B
posted few photos at
http://w5aj.eqth.net/drake/drake.htm
Observations:
The air cooling / fan is anemic
The plastic fan & metal hub can be rejoined with Gorilla EXPOXY Glue
The undated W5DDW fan article covers parts that are now obsolete.. even
blowerwheel dot com has no direct replacement
The amp hums bit loud on SSB position
The control/filament connector at back of the Amp section is amazing,
lasting 50+ years, difficult to push on, the connections are tight!
The connector for activating the amps T/R relay seems unique. None came
with this amp
For 50+ year old amp, not bad
Did I mention the cooling air is uninspiring..
