6 Ei 6DJ8 ECC88 A-Frame Yugoslavia 1970s Vacuum Tubes -
$90 $75 shipped (in USA)
NOTE - the photo shows 9 tubes, but the last three have been sold.
Offered on behalf of a third party is a group of six Ei-made 6DJ8 ECC88 vaccum tubes.
All six tubes have an identical internal A-Frame construction and a crosshatch on top of the glass (although the crosshatching is more distinct on some tubes than others).
Tubes #1-5 are labeled PRO/COMM 6922 E88CC, and Tube #6 is labeled Penta E88CC. Regardless of the label on the tubes, these are all Ei Yugoslavia ECC88/6DJ8s (not 6922 E88CC).
Most of the tubes have a small code near the base of the tubes (which is difficult to read in most cases). On Tubes #1-6, a part of the code is "O7" (the "O" has a dot in it).
Based on what information I can find, I believe these are all 1970s production, and were made using Philips (Holland) machinery. They also have a very good reputation – just a notch below Amperex and Telefunken, and certainly better than similar current production tubes.
I tested these on my Weston 981 III, where min (65%) is 1350, making about 2075 "theoretical" 100% (Gm = 6X meter). The results are as follows (rounded off to the nearest 50):
Tube #1 2600/2700
Tube #2 2400/2450
Tube #3 2550/2400
Tube #4 2500/2500
Tube #5 2700/2550
Tube #6 2600/2600
Tube #7 sold
Tube #8 sold
Tube #9 sold
This is definitely a nice, strong group. Based on these results, you should be able to make a quad and a pair (or three pairs).
I might be willing to split the group for the right offer.
I can provide additional information or pictures upon request.
