FS: 6H30 DR Tubes all SOLD!


Recommended Posts

Here are 4 of these from the early 70's! Super rare, test way higher than any Sovtek/EH version of this tube. All have been run tested in my NOS Valves NBS preamp with no problems at all. I bought them as NOS, but I can't say they are. They do test very high and are quiet tubes. I never used the ones I have here for sale, only tested. Matching is not super tight, but the sound was perfect and balanced through the preamp. Tested with a TV-7 tube tester, as a 6DJ8, increased the bias, and used the E range. Works well for this tube. All tubes are same print style and construction as the pictured tube. Nice print on all.


$125 shipped each CONUS. You may take your pick or buy all 4 for a slight discount. First PM first served, etc. ALL SOLD!
