Just another accolade for the Astron PS. I bought a 35VM in 1980 to
run my then new TS-180S and it has worked over the years without fail
until last year when a couple pass transistors finally died...that is
34-years without failure!

It is amazing how many times I've found this to exist and how many times
that I've written about this on various reflectors. The power coat paint on
the chassis makes for an excellent insulator.

Sorry about my mis-typing of POWER and POWDER... Dang, that's the

Yes conductive POWDER coating material is available, however it is more
expensive and more difficult to use.When I worked for the JA's ,
how well I know,
First of all, it is POWDER coating not POWER coating. Secondly you can get
conductive POWDER coating material.
Unusual to find such and many people do not like to use it.

My suggestion and test is to measure the voltage between the Astron
power supply GRD terminal and the GRD terminal on the radio. Any value
over 0.5 volts, when in CW mode, key down at 100 watts is a situation
that should be investigated and improved.

Hi Peter,
I bought the Astron RS-35M for my $4000 K3 in 2008. I've never turned it off
and I've never even given it a second thought. No fan, no RF noise, just

An Astron SS-30M is a much better supply and will supply the required
current. It has excellent regulation and IS NOT a noise generator.
Plus it has a volt meter and amp meter on the front panel.
