Exemplar 3910

Help!!! Which brand of 6829 or other tube is making your Exemplar 3910 create the WOW factor
I have an Exemplar 2900 that uses those tubes. I upgraded to the Amperex 7602. Instant WOW factor, but even better after a proper break in.
thanks for the reply, who/where did you purchase those tubes
You can get then from Andy at Vintage Tube Services. It's best to contact him by phone (616-454-3467).
Styxtrekr. I was in error with the number I gave you. It's an Amperex 7062, not 7602. Sorry. Jeff
