Default FS: Pairs of 6N30P-DR Supertubes, 1983 vintage

I have two closely matching pairs of Reflektor 6N30P-DR supertubes.

All have production code of 05 83.

Come in original blue and yellow boxes.

These were tested on an Amplitrex tube tester at 250 plate volts, 10mA plate current. New testing results would be grid voltage(EG1) of 14.4v and transconductance (Gm) of 5.8 mA/v (5,800 microhmos).

Pair 1 Triode 1 Triode 2
EG1 Gm EG1 Gm
1 15.4 7.3 15.5 7.2
2 15.6 6.97 15.5 7.41

Pair 2

1 15.4 6.96 15.5 6.8
2 15.7 6.85 15.2 7.5

Sold AS IS, but these have had no hours put on them since their testing.

These are the last of my 6N30 tubes, and the closest testing I ever saw on an Amplitrex, especially compared to the 6H30 tubes that are being produced currently.

Asking price is $225 per pair, including USA shipping.

International shipping at cost via USPS Priority Mail.

Paypal payment preferred.

Please PM me if interested.

Excellent sounding tubes at a fair price. I have one in my pre-amp and it made all the difference in the world over the stock tube that was in there.

Time to buy up 6n6p and 6n1p tubes before they become "rare audiophile" items. These russian tubes are dime a dozen in any electronics surplus outlets in former USSR territor, including 6n30.

Well, 6N30P is not that easy to buy cheaper and even sources from Ukraine , Russia don't list them very often and certainly not cheap . Do you have a place to buy from you'd like to share??

On ebay there's a seller ftom Lithuania I believe, wbtubes, I used to buy batches from them. Not entirely sure about current supply of 6n30 though. With more recent manufacturers adopting 6n6p and 6n30 all the suppliers are catching up fast with their pricing. I will make sure to visit them on my next trip to the EU.
