These are a matched quad of Chinese Silver Eagle II KT88 output tubes. Am selling for a friend who is a compulsive tube roller, who used them for about 35 hours. Tubes will be in re-issued Gold Lion boxes. $42 for the quad, which include paypal fees and shipping to the U.S. 48 contiguous states. Please contact me for shipping estimate to other locations.

Now, that's a good price for KT88s. -

These are a matched quad of slightly used 1960s Sylvania 6BQ5/EL84 output tubes from my reserve stash. On one of my Sencore TC162 testers, the emissions results are 99 for three and 98 for one. These are very strong readings. A typical new production 6BQ5/EL84 usually test between 97-102 on the same tester. The quad also pass the life test, grid leakage and shorts tests. I've had them in storage for a long time and recently sound tested them. The quad are very quiet. I've decided to sell them since I have other quad reserves and will never be able to use them all. Here's your chance to get some very nice Sylvania black plates. $64 for the quad, which include paypal fees and shipping blah, blah, blah. -
SOLD!
