[TenTec] Titan 425 shelved for 10 years

[Joe Giacobello]

I agree.  I purchased two sparingly used Titans several years ago.  In each case, the electrolytics were failing one at a time.  After replacing several in each unit, I decided to bite the bullet and just replace all of them.  It's an easy replacement since they are screw mounted.  I believe Mouser and/or Digi-key has the best price on replacements.

The best of electrolytics don't store well for a decade. They might
recover or they might blow up. To recover them they need to have the
voltage brought up slowly with current limiting. When they blow, the
fill their area with shredded aluminum foil, accompanied by shredded
crepe paper filled with electrolyte, and spray some of the electrolyte
about. After cleaning up a couple, I prefer to BUY and install new
electrolytics with a current date code, no more than one year old.

As for the tubes, it would be to their benefit to run for a day or two
with only filament power. That will let the getter grab gas that has
leaked in and will cook gas out of the emitting surface. Both will give
the tubes far longer life.
