[Amps] Ten Tec Titan 425 Options

[Carl]

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.
