I recently aquired a huge collection of NOS tubes - I have a little bit of everything. I am a electrical engineer and have been doing my best to buff up on tubes. In addition, I have a Hickok 539C that will be for sale once all the tubes sell - probably about 6 months :) I have also starting building some kits and I will post my trials and tribulations. Below is the link to the list. If you are interested in certain ones, just email me, and I will email pictures, test results, and any other information required. I will post some pictures of some of the highlights.

**We are only about half-way through the collection. So the list will probably not be complete until sometime next week.

Format of the list is: Brand - Tube Type - Tube Type - Quantity

I would also be willing to trade for high quality chassis, knobs, audio grade resistors, audio grade caps, high quality connectors,.......

i sent you a pm regarding quite a few tubes yesterday. how much would i be looking at for all the 12au7s?


RCA 5814A - Blackplate Two Mica Halo getter - $20/tube - 7 available
RCA 5963 - Grayplate Halo Getter - $15/tube - 2 available
RCA 12AU7A - Grayplate Halo Getter - $15/tube - 2 available
RCA Command 5814A - Blackplate Halo Getter - $20/tube - 4 availble
RCA 12AU7A/ECC82 - Cleartop Side getter - $20/tube - 6 availble
Amperex ECC186/7316 - Orange Globe Label Holland Halo Getter - $50/tube - 5 available
Amperex 12AU7A Bugle Boy - Holland - Halo Getter - $70
QUAD FACTORY MATCHED Bugle Boy - $500 for the quad set
Telefunken Factory Matched Pair - $250
Still working on a price for the matched pair Amperex Orange Label

If you think any of the pricing is out of line, please say so and post why. I would offer 20% off if all were purchased together. I would test all tubes prior to shipment and email and post results. I would offer returns on tubes if you are in the US. The returned tubes would have to test at same values as when they left my possesion. You would have 3 days to inspect tubes. Shipping would be $10 for USA.

IN ADDITION, I AM GOING TO DONATE 10% OF ANY SALE GENERATED THROUGH DIYAUDIO.COM TO DIYAUDIO.COM.
