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!
On my last job (retired in 2009) we had lots of Astron 20A's on board
ships to run both HF and VHF Marine radios and they also survived
well. We did lose a few when the ship's ac generator surged to
160vac. But that is not an uncommon situation on ships so they did
well considering.
I now run my station on a single Astron 50A which feeds thru some No.
6 welding wire to a 30A Buss master fuse. 14.2vdc at the PS is
delivered as 13.7vdc at the radio shelf and runs a number of 100-170w
amps and radios. Load usually doesn't exceed about 15A.
I do have a 300w sspa but it runs on 28vdc and loads to 18A at full
power (using a surplus MOT repeater PS). The 1kw 6m amp (surplus
ch.2 TV driver) runs from a 50v-50A switching supply which runs off
240vac. You know that amp is very linear if it was used on TV.
