Sources for Parts?

What is a good source for parts to re-cap old gear? I do know about hayseed hamfest, but they
seem to just specialize in filter cap cans.

Thanks,
Chris

Yep, that's sort of the home- technician standard place for ordering repair parts. They have just about everything one would reasonably need to restore most tube audio gear.

Even most of the pros use their wholesale/business-only-sales division- CE Distribution.

What's not available from them, can sometimes be found at Mouser and Digikey...

Some places specialize in some types of parts- Hayseed Hamfest,as mentioned, is one example- they make multi-section caps. Can be a life-saver to a difficult repair, if no one else has the right values. More expensive than AES, but they can make any reasonably normal permutation of a can capacitor, in terms of number of sections, values and voltage.

There are also some surplus electronic places, that can sometime supply weird, obsolete things like non-standard value caps, weird switches and such. Surplus Electronic Sales, Electronic Goldmine, Electronic Surplus, Skycraft and others are some where I've found a needed tidbit here and there over they years.

Good answer also. The difference is that if you want modern FP style electrolytic capacitors, you can get them from Antique Electronic Supply. I have used their JJ electrolytic capacitors many times. They test excellent for value and leakage at the working voltage. The only downside may be that you need to purchase a clamp because the JJ (and some others that they sell) are not Twist-Lock style of mounting. AES has an adequate supply of film capacitors and resistors so it can be your "One Stop Shopping" choice since shipping costs have gone into the stratosphere.

I use Digi-Key and Mouser if I want specific parts like those thin electrolytic capacitors when I "stuff" an electrolytic can capacitor. They also have good name brand products which do have datasheets instead of back room parts.

Digi-Key not only has a great selection but they have a free shipping option which is especially helpful when you only need a few things. Otherwise the shipping can cost more than the parts. As far as I know, of all the vendors mentioned, they are the only one that offers free shipping with no minimum order.

If I have space I use individual caps underneath and leave the old can (disconnected) in place for looks. Replacement cans are convenient but expensive - often 4x or 5x or more than the cost of very high quality individual caps. I look for caps that are rated 105° for 10,000 hours. If you really need a can, Hayseed stuff$ theirs with high quality individual caps. Many other replacement cans have rather unimpressive specs.
 
I'm planning on using using a couple of cheap aluminium bottles with the tops cut off as replacement 'cans' planning on stuffing them with polypropylene caps rated for 100,000 hours.

I’m curious . . . what amp are you planning to use them in?

Vintage tube gear doesn’t typically allow the use of film caps in the power supply due to space constraints. As always, I'm sure there are exceptions. Some amps pulled from consoles have a lot of room both underneath and topside. But if you’re replacing one or more typical vintage electrolytic PS cans (multiple sections / 22uf, 33uf, 47uf 450v, for example) films are usually not a viable option.

Your cans must be either much larger than typical electrolytic can caps or you must be using film caps with lower capacitance and voltage ratings.

I’ve been using films in DIY builds, for example:


Films aren’t bothered by heat so much so, if you have the space, there’s no concern mounting them inside the chassis.
