REcap kits

I'm interested in recapping a Harmon Kardon TA224. The amp has been in the family since 1971, and not too many years ago I fired it up and started using it. Soon I had to replace a tube, and just recently the rectifier diode pair (the grounded one shorted). The improvement in sound quality was remarkable after that, and so I have thought that replacing at least the can type electrolytic capacitors would be a good thing. I'm wondering about kits and if anyone has some thoughts on reliable, good suppliers. I've not adverse to hunting down the parts on my own, but at the outset thought I might at least determine if there is a reasonably priced, and easier, altrnative.

I do have a photocopy of the HK Instructional Manual I got online, that has an excellent schematic but a very partial parts list. I can't tell from ebay site but the Howard Sam's "service" manual would seem to promise more. For $5 what's not to like? Thanks much! I'm already getting the feeling that wandering around on Mouser or Digikey or the like with a good parts list in hand, along with some good Youtubes perhaps on what I'm getting myself into, might be a reasonably reliable way to go?
 
Hope you were able to get it. I see it sold today when checking just now.
Yes the Sam’s service manuals are pretty nice copies of the originals. Supplied all the shops with them.
The can caps can be made up by Hayseed if need be.
Good luck!
 
If Sam's has the BOM list, go onto DigiKey or Mouser, Parts Connection.....etc to order the parts, and avoid the fleaBay characters selling recap kits; who have dubious and sordid selling history; as mentioned above.

Plus, as an option there should also be enough room underneath inside the chassis to bundle individual caps in place of the multi cans, in case you don't want to spend the money on new cans which stand out and cost can add up, and want to keep the orig. look of the ones already in place. Good luck

Yes I think it must be my purchase of Sam's service manual! Ha. I didn't even notice there was only one left. I looked over can values etc. and put in quotes to Hayseed, just to see what we're talking about. Checked out CE manufacturing as well. a couple of their cans would work, maybe. There's a height requirement for the HK that many seem to exceed. I'm sure I'm going to avoid the kit route now. Thanks so much!
 
If you were to ever place the chassis into a cabinet the height of the can is critical.

Glad you were able to get the manual. I think you will like it.
 
If you aren't concerned with maintaining the can cap appearance, these multi-cap boards from MSquared Circuits in Canada are really nice. They allow you to replace the cans using modern electrolytic caps. Much shorter than any can, so no height issues.

These have pads for soldering test points also, which I've added to this one.

Yes, I remembered the height. I usually blank on something critical like that. Those cap boards really look intriguing, I'll check it out. Thanks for the tip. Yes, this is my first venture into restoration, nomenclature correction noted.
