I've got the Corsair II on the bench for a PTO cleaning or possible rebuild. While I'm at it, I'm considering a) complete realignment b) replace any components that may go out of spec due to age (wou

Miniature electrolytics are ripe for replacement due to old age. Go for low ESR high temperature rated for the best performance and long life. Don't forget those on the display board. I doubt Tentec
The BFO/carrier oscillator crystals may have aged and the 15.3 MHz oscillator (L4) which centers the passband tuning may need adjustment. This you can do by ear, but the BFO frequencies require the u
There may be a valid reason to clean up and tighten the PTO drive, but I wouldn't recommend doing any of the other things you mentioned unless you have evidence of need. Phil C. Sr. k4dpk ___________

At this point, 30 years old, those TT PTO rigs are "the new boatanchors" and I am of a mind that it pays to think in terms of restoration...it's about that time. I have gone through a couple Tritons,

As did most makers, just on price. But I've bought NEW miniature GP electrolytics that didn't pass my power factor test fresh out of the sack. Electrolytics don't age gracefully when not powered, but
Check out this list. http://www.nichicon.co.jp/english/products/alm_mini/list_f.htm You can find a lot of these "P" series Nichicons on ebay in lots for cheap. Try to spot the date codes in the pics.
My ears hurt when I heard "boatanchor" and Corsair II used in the same sentence, but it's probably true. As I sit here cleaning the PTO, I'm reminded there's nothing out there being made like this a

When not going through authorized distributors it is possible to pick up counterfeit parts made to emulate good parts or good parts that are old or didn't pass inspection. That's most hazardous when
Hi there, It's great to hear and feel your feelings about the RTO and its makeup.... I am also very glad to hear the your keeping up with the rebuilding and ball bearings. When you are finished - you
Joe, I'd love to but can't figure it out. Not being in the US, I have to get it from an eBay store. There are several that sell Deoxit products, but none that are very clear which one they sell is th
I use a 5% Oleic Acid and 95% Naptha mixture which works great and you can buy a lifetime supply for about the same price of a bottle of the name-brand stuff. You can also mix up a stronger mixture a

I suppose that's a working brew, but Caig admits to no naptha in the pure DeoxIT bottles, like D100L, in fact admits nothing in the MSDS except a flash point above 482 F. The spray version they admit
Perhaps the word "classic" is more accurate than "boatanchor"...they are not that heavy after all. Back in the 80s, I was replacing Sprague Atoms, Cornell-Dubilier "Beavers," Tiny Chiefs, Bumble Bees

Mouser carries Vishay-Sprague Atoms. They seem to be the same high quality they originally were. Much larger for better heat dissipation than the miniatures too. I hadn't considered drilling new hole
I believe they are now a big can with a little cap tucked inside. I use them in guitar amps, which is probably their biggest market. They are now super light for the size...used to be they felt like
It is pretty hard to get anything out of Caig about their formula (understandably, I would not give it out either). I have been using the oleic acid / naptha mixture for years now and it has never le
