I am continuing to sell off my collection of CDM tubes that remain in my collection to fund further research.
Now I've gone through everything I have left and updated the list.
Most of the tubes are those that I had as a spare pair. Many of them were auditioned by my friends and came back to me recently. A few more will come back later and be added to the list if I decide to let them go.

Below is everything that is available with prices for each pair (2 pieces).

01. General Electric JG-6021, matched pair - 200
02. General Electric AF-6111A, matched pair - 300

03. United Electron 6BF7W - 130

04. Sylvania 6111 Gold Brand, matched pair- 140 (2 pairs)
05. Sylvania 6021 Green Vintage, matched pair - 150
06. Sylvania 6BG7 Green Vintage, matched pair - 150

07. RCA 6021, matched pair - 120.

These 7 pairs are shown in the photo.
A few more pairs are listed below, photos of which I will add later.

01. General Electric AF-6112A, matched pair - 250

02. Sonotone 5718/6AK4, matched pair - 200
03. Sonotone 5719, matched pair - 200
04. Sonotone 5840, matched pair - 250

05. Sylvania/Philips 6021 Green - 80
06. Raytheon 6832 Red - 100
07. Raytheon 6111 Red - 100
08. Mullard 6021 military Grade - matched pair - 90

09. Sylvania 5977 Gold Brand, matching pair - 120 (soldered on a black double triode PCB, which allows you not to worry about the left or right side of the device).

All prices are in dollars. If you want to buy several pairs at once, I can give you a discount.

I'm also returning some tubes that are currently being listened to by my friends. In this case, the list will be supplemented.

Ask me anything in PM.

Thank you.
