Hi folks, while we're under lockdown/have endless time for hobbies I've returned to my amplifier building plans.
I've been collecting tubes and useful transformers for years with the pipedream of designing a roughly 10-20WPC PP tube amp. I've accumulated a whole pile of tubes and yet still not a nice set of tubes for a stereo amp.
I'll attach a list of all the valves I've piled up with the hopes that one of you may need a few/lot of them in exchange for perhaps a quad of power tubes and/or pair of OPTs with suited impedance, I'm new to designing circuits so looking for something with more support/published circuits than a lot of the older tubes I've found.

Was thinking of hocking some of the rarer ones on fleabay to pay for the parts but I'm a big fan of this forum and the idea of building it entirely via finding/trading is better suited to this cheapskate 🙂 Also, I'm based in Melbourne, Australia so postage for heavy transformers is a pain so posting from US/EU isnt ideal.
I have some pictures of them all but just ask for more details on anything.
BTW if anyone sees anything they need and don't have anything to trade just ask, if I can't see anything else to do with it then it's yours for price of postage, or post a beer back in return 🙂
Cheers!

Also forgot to post them but here's some photos of the tubes and some transformers I've got around, most of which I'm keen to trade for parts/sell or just help people out if they need them, cheers 🙂

Hey so just an update/a few more tubes I found in old boxes.
Trying to juggle multiple trades with different people to get matching parts for an amp was difficult so I'm looking to just sell the tubes to fund the build. (although if there's anyone with a quad of EL34s and 6SN7's I'd love to trade for sure!)
More tubes I've got:
GZ34/5AR4 - amperex(bugle boy)
5AR4 - Mullard
6080 - GE(metal base)
ECC88/6DJ8 - Amperex(gold)
ECC88/6DJ8 - Amperex(bugle boy) (5X)
12AT7 - Telefunken (3X)
12AU7 - Amperex(bugle boy)
12B4A - GE
12B4A - HP (3X)
CV358 - Mullard(red)
85A1 - Mullard (3X)
6SH7 - HP(metal)
Feel free to pm to make me an offer or ask for more details/photos. I'm looking to sell/give away pretty much everything so I don't have any bits left over to temp me into building another amp 😛
Pictures(sorry the extra handful in this post are not pictured, I can take photos if need be):

Thanks LAD
Any specs on the transformers?
Id also be interested in the 6CA7 and the 2 x Brimar 5U4 tubes if not sold

Yes they're still here 🙂
As for the trannies:
The big one down the bottom is 575-0-575V @250mA rectified, 6.3V @4A, 5V @4A
The upside down grey one is a HP tranny I plan to use
The copper wrapped one next to it is a HP/Paeco 910-123, 320-0-320V @ 65mA rectified, 5V @2A, 6.3V @4.5A
The upside down one with grey bells and back laminations is a A&R 1892, 385-0-385V @100mA rectified, 5V @2A, 6.3V @2A, 3.15-0-3.15V @2A
The big black Kenyon one is a S-24537 a mystery to me, couldnt find data on it/havent bothered testing its various pots.
The second Kenton is a T-153 choke, 30H, 90mA, 350ohm
The top Kenyon is just a 6.3V heater supply I may end up using
I don't have any details on the Trimax and haven't tested it yet however I'd guess it's pretty similar to the HP 910's specs.

Sorry for double post, I have a couple of other transformers sitting around:
A massive A&R, with a powdercoat grey bell on one side: 565-0-565V, 500-0-500V or 425-0425V @250mA rectified, 2X6.3V @3A, 5V @3A, 2X2.5V @3A (put a picture up in the link below) and also a Tektronix 120-117 transformer in great condition (can get pics if needed).
Here's some photos of the tubes/transformer:
