Am selling a pair of popular Raytheon 5814 double mica blackplate D getter tubes which I bought in May and tried out for a week or so in my system.
Excellent sounding 12Au7 substitute.
These were quiet in my Audio Mirror PP1 preamp line stage.
Testing info from the buyer was:
2600/2600 & 2600/2650 WHERE NEW IS 2200 ON HICKOK 600A.
Matching date codes are 57-23.
I am selling these as used and if you are dissatisfied for any reason you can return for full refund minus shipping.
Reason for selling is they sound almost indistinguishable from my CBS-Hytron 5814's (maybe slightly more neutral) and I am simply looking for something a little different.
56$ shipped via USPS Priority Mail to conUSA. Foreign shipping pays any extra expense over 6$.
PayPal only. No fees.
Will also consider trades for interesting used or NOS western European 12Au7 pairs.
Thanks for looking.
I have perfect feedback on AGon (Lkdog) and Ebay (Hoopdoggydog).
