[Amps] Ten Tec Titan 425 Options

[Jim W7RY]

WOW!  $800.00 for a set of caps?  Sure doesn't seem very "square" to me.

The plate voltage is less than 2500 volts on a Titan, and as I remember, 
there are 8 caps in it. A set of caps would set you back $80.00 max from 
Mouser. www.mouser.com Jeff at Harbach has the screw terminal type like used 
in the Titan.

How many diodes are in the string now? Don’t need more that about 5 in each 
string.

I would fix it myself!

73 and let us know

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
