friends;
I have a couple of 50s era Fender tweeds on the bench for restoration. to that end I'm searching for the following in yellow:
.02uf @ 400V
.1uf @ 400V
also interested in earlier paper wrapped Astron type AM @ 600V in red or white, similar values including .05uf.
I'm familiar with the current offerings on Ebay. got any dead Astron filter caps ? I may be interested in those as well to re-stuff.
trading ? I may have something to suit your needs
TIA
jerry

just safety observation slightly ontopic: using old capacitors mean searching for the troubles (DC leaking, humidity soaking through the leads, cracking etc etc)
thanks for that. I am familiar with the Jupiter product but this was a new one on me. for the clones I build I usually have good luck with
NOS glass sealed PIO types.

point taken.
a further consideration involves the small fortune I spent buying "NOS" caps before I had a tester on site.
I shudder to think how much of that went out in the trash.
Those RECPRO caps - nice idea, but I'd rather use Mallory 150's and pocket the $28 a cap saving. Plenty of good caps out there for a reasonable price. I'd look at Zoso before I'd go this route. Spending $300-400 on caps when that's only one ingredient in the tweed sound recipe seems quite foolish to me. I built a tweed Tremolux with scavenged and NOS AB carbon comp resistors I had on hand and some of the blue molded Ajax caps I had collected that had no leakage on any of them. I used Mercury transformers, Gavitt wire, the spacing off a 55 tremolux board and exact lead dress. Also a Weber A125 alnico 12 and built a solid Walnut finger-jointed cabinet - the one intentional departure. Thought I couldn't get much closer. It sounds great, but does not quite have the sonic signature like my Harvard. Its brighter. Maybe it needs 60 years to get there. Either way, I doubt these caps would be the missing link to get me there.

That’s a lot of wind to express doubt . Try ‘em and let me know what you think. I like them better than Mallory 150s my 2 cents . Do you.
