FB, Larry. I think you will be better off with the new supply. Better to be
safe than sorry. No sense taking the risk with the new rig no more than the new
supply costs. Good luck with the new station.
Ten-Tec sold an accessory or aftermarket over voltage protection circuit that
was used in line with the 252/262 power supplies, model #1150, that killed the
output of the supply in the event of high voltage conditions. No longer
available from Ten-Tec but sometimes found on the used market. I have a
schematic for one of these and info about building this OVP circuit yourself,
courtesy of Pete, W6JFR. Just a handful of parts and could be done inline or
inside the supply. Would be glad to copy this and send it to you if you like.
The 252/262's had over-current protection but at 18-20 amps. I suppose you
could use a 7 amp Airpax circuit breaker inline to protect the Argo V in the
event you were drawing high current thru the finals such as a high SWR
condition.
I didn't know anything about this less than a year ago so we owe it all to the
fine inhabitants of this reflector who are much more knowledgeable about this
stuff than I'll ever pretend to be!

Subject: [TenTec] More about power supply for my Argo V
After reading Edward's comments, I became aware of an issue wit my 252 M0.
I phoned TT technical dept. and spoke to a tech who actually repairs Argos. I
was again informed that I should not use the power supply that I have. So, I
went ahead and orderd a new one. Thanks again to Edward and all those
responded, without the negative comments, I would not have been aware of a
potiential problem. Larry GreenbergN5BEA
