[Hallicrafters] Chassis Cleaning ... etc.

[GARDGORE at aol.com]

I cleaned and went through twenty receivers here this past year so eventually 
you get things down to a system I guess. I bought a big powerful Sears 
shopvac just for this task. I have never used it for vacuuming so it is 
always clean inside. I have the hose on the discharge side and with the blow 
nozzle attached it puts out a pretty powerful jet of air. If I don't want so 
much pressure due to the presence of decals and paper labels, etc., I can 
remove the nozzle and blow from the end of the hose which calms it down quite 
a bit. I always work on a cardtable on the deck outside due to the amount of 
dust that is likely to be blown out. The usual drill for new acquisitions 
here is to blow them out a little first to make disassembly a little easier. 
I then disassemble as much as is practical using muffin trays to organize 
hardware. If you are not planning to align right away be sure to mark tubes 
for location if several are the same number. It's easy to finish the job now 
with the chassis out on the cardtable again using an assortment of brushes 
and the vacuum cleaner. Be sure to tape over the metal bands if your brushes 
have them to prevent accidentally scratching the IF cans etc. Be really 
careful around paper tags and labels. I usually tape clear plastic over them 
first because they are so fragile. There's much more involved than this for 
proper cleaning of course but this will get you started.
