There is no need to use 400uF caps and the 270uF used by Ameritron in their
1500W + amps will run you about $120 for all 8.
The diodes are about .25 each.
Labor to do that is minimal but since that RF section is such a PITA to work
on and one of the screwiest designs around there is no telling what else
may be needed. Its not an amp for someone not ready to do his own work.
And dont even to think about the manual, there are 2 versions and Ive yet to
see a correct one.
If luck is with you its under $150 in parts and maybe $75-100 in labor if
its just the caps, diodes and replace a bunch of resistors.

Subject: [Amps] Ten Tec Titan 425 Options
A little over a year ago I acquired a working Ten Tec Titan 425. It spent
a
year in the closet as I had nothing to load it into. I finally got the
new
antenna up and turned on the amplifier. After about 30 minutes the fuses
popped and the amp was dead.
I took it to Burghardt Radio Repair and Jim said the transformer was good,
but most of the rest of the supply was toast. I believe him as he has
always been fair and square with me.
He said there was a mod that added another diode to each leg of the bridge
that probably would have saved me. I paid him for the diagnosis and
brought
the amp and supply home. The bad news is the caps alone are around $800.
Other parts, labor and I am probably looking at $1200 or more. I don't
have
that kind of cash and if I did I'm not sure this would be the most
effective
way to spend it. So, I am trying to figure out my options.
Any suggestions?
Thanks and 73,
Joe kk0sd
