RCA RED BASE 5691/5692, TUNG-SOL 6SL7WGT AND GE/RCA 5693 (RED METAL 6SJ7)
5691s and 5692s are sold. Other tubes are still available.I have several tubes for sale in this listing. Prices are per tube unless otherwise stated. Shipping and Paypal fee are extra (see Terms and Conditions below).
I may consider a discount for larger purchases. For example, everything
remaining in this listing as a group would be
$750 $175.
I might consider trade, but I have very few needs and it would need to be a pretty good deal. A room-correcting preamp would be of interest (Copland or DEQX), but of course I would need to add value. In any event, it does not hurt to ask.
All tubes were double tested for Gm (except for the 5693 as indicated below).
I first used my Westmore 501, which is a government version of the Triplett 3444. I then rechecked on a reasonably calibrated B&K 550.
For 5692 on the Westmore, average new is 2200 and reject is 1400, while on the B&K average new is 2600.
For 5691 on the Westmore, average new is 1600 and reject is 1000, while in the B&K average new is 1600.
On the B&K, the settings for 6SL7 are the same as 5691. On the Westmore, the settings are slightly different but the average new and reject are the same, so I was lazy and tested the 6SL7WGTs as 5691s.
Just for information, Triode #1 on the Westmore is Triode #2 on the B&K (and
vice versa).
All tubes tested were clean for shorts/leakage on both testers.
Further information and results are below.
RCA Red Base JAN-CRC-5692 - SOLD
There are 5 of these. They come in white boxes. Date codes and test results are as follows:
Tube #1 4-43 Westmore – 2225/2275 B&K – 2950/2900
Tube #2 56-43 Westmore – 2675/2450 B&K – 2950/3450
Tube #3 4-39 Westmore – 2400/2300 B&K – 2950/3000
Tube #4 3-43 Westmore – 2450/2325 B&K – 3000/3300
Tube #5 2(?)-43 Westmore – 2225/2250 B&K – 2750/2750
All results correlate very well between the two testers, and all tubes test “like new”.
RCA Red Base 5691 - $SOLD
There are three of these. Tubes #1 and #2 are RCA branded, and have dull black plates. Tube #3 is GE branded, and has shiny black plates. Date codes and test results are as follows:
Tube #1 3-52 Westmore – 1700/1650 B&K – 1800/1900
Tube #2 59-09 Westmore – 1575/1600 B&K – 1800/1800
Tube #3 NL Westmore – 1550/1700 B&K – 1900/1750
Again, all results correlate very well between the two testers, and all tubes test “like new”.
Tung-Sol 6SL7WGT (Raytheon Branded CK5691) - $50/pair
These are Raytheon branded CK5691s, but clearly appear to be Tung-Sol brown base 6SL7WGT as they have flat grey plates and large halo getters. I could not find any date codes on these, but they are believed to be from the early 1960s. Test results are as follows:
Tube #1 Westmore – 1525/1550 B&K – 1800/1800
Tube #2 Westmore – 1550/1575 B&K – 1900/1850
These two tubes make a reasonably matched and balanced pair.
GE and RCA Red Metal 5693 (Special 6SJ7) - $20 each
I have seven of the GE and two of the RCA. As of this point I have not tested these, but all other 5693s from this group tested like new. I will test on the B&K prior to completion of purchase. Buy all 9 for the price of 8 (assuming they all test out).
