One matched quartet of 12AX7's and one matched quartet of 12AT7's. Additionally, each pair of triode sections within each tube were matched.
Bought these two months ago from Tube Depot for my McIntosh MC2102 on the strength of the experience others had in their amplifiers. They did not work as well as I'd hoped in my amp, so am letting go of them. I am, however, keeping a set of four that is working beautifully in the phono stage of my McIntosh C2200 preamp.
The price of each tube when new, including testing and matching, was $22.95. These have less than 50 hours of use on them and McIntosh gear is known for being gentle on tubes.
My asking prices are as follows.
A pair of the same kind: $32
A quartet of the same kind: $60
Both quartets (all 8 tubes): $100
Given I am including shipping via USPS Priority, I think my asking prices are fair. Lowball offers will be ignored. Sorry, but I will not ship outside of the US.
