I've been looking through the stock of tubes I have and decided to put some of them up for sale as I'm not using them. All tubes are matched pairs, which makes their value higher. Some of them were heated for several hours, some were not used at all and were only tested.

They are all soldered to the PCBs, so you just need to install them in your CDM and enjoy. I will also consider an trade for other similar tubes of other brands.

I write the price for each pair separately, if you don't need the whole set, you can choose one or more of them. However, I would prefer to sell them all at once.

National 6021 - 160
Philips 6021 Green Brand - 80
Sylvania 6111 Gold Brand - 130
General Electric AF-6111 - 270
Raytheon 6832 Red Brand - 100
Toshiba M-6021 - 300.

I will give a small discount for multiple pair purchases.

Price include Paypal tax and do not include shipping costs.
Feel free to ask me in PM.
