Subject: Re: [TenTec] Titan info
Hi Bob and congrats on getting your hands on a darned good amp. I've had =
mine for seven years and other than having to replace vacuum relays =
often, it's worked great for me. I typically wear out a vacuum relay a =
year, but then I'm pushing the thing at greater than 60 wpm also.
Two thing's I recommend:
1) Get in the habit of an annual cleaning. Take the top cover off =
and use a rather stiff paint brush and your XYL's vacuum and REALLY =
clean the dust/dirt out of it. I go so far as removing the tubes and =
dusting the sockets and in the chamber underneath the tubes. I also use =
a small brush and clean the vanes on the fan. I also cut out small =
pieces of air conditioner foam and attach it to the air intake louvers =
on each side of them amp, with several pieces of sewing thread. During =
contest or extended periods of operating, I direct an external fan on =
the power supply. All of this cleaning takes you about an hour a =
year..but sure helps in keeping the air flow strong on the $400 a piece =
tubes!
2) At ham fest, etc., look for some GOOD Jennings military type =
vacuum relays. Buy SEVERAL of them and keep them handy.
Don't be afraid to run at 1500 watts output. I've done it many times on =
80 mtrs during the CQ WW DX contest. It just sits there and kicks tu-tu!
