FREE SHIPPING AY MY ASKING PRICE PRICE OF $105.00

Item Description:

I bought these tubes a few months ago as NOS, see below:

I used them in a Decware Mini-Torii, a 3.3-watt amp, for a few hundred hours.

The 12AU7 tubes only become warm, not hot, in the Decware amp (thus, low stress on the tubes).

I sent these tubes to Brent Jessee Recording for ADDITIONAL testing, Brent confirmed that they are a MATCHED PAIR and near to NOS in use (within 75% of being NOS): Valvo 12AU7 68-65 and 69-69. This would be about 75% or so of new.

This is a quiet very nice perfect matched set that is priced to sell.

BID WITH CONFIDENCE I HAVE 100% POSITIVE FEED BACK ON AUDIOGON AND EBAY USERNAME: ALFA_LOVER.

If you use PayPal add 3.1% to the price.

ORIGINAL AUDIOGON LISTING:

Mullard Blackburn 12AU7 ECC82 NIB/NOS best pair!

All tubes were tested on my calibrated TV-7D/U tube tester on shorts and grid leakage.

MIn.good for 12AU7/ECC82 is 56=65% or 86=100%.

I have one matched pair of Mullard (in Valvo label) 12AU7/ECC82 NIB/NOS tubes for sale at $135/pair.

These are the authentic Mullard Blackburn plant tubes made in 60's with "Gf2/B3J5" and "Gf2/B8E5"etched codes.

They scored 108/112 and 104/101---strong, balanced and closely matched pair! For the legendary Mullard Blackburn tubes, these are as good as you can get.
