Miss the OTL so much. If I'd known it would work with those old ass tubes I would still probably keep it.

Hi George, nice to see you here.

I use the GEC 6AS7 tubes that I got from you on special occasions.

Maybe tonight to listen to a couple of DSD albums would be a good time.

The Marconi-Osram/GEC VR102/BL63... Shown below next to a 6F8G. It is easy to see why some refer to it as a 6F8G on steroids. lol :)

The heater draws 1.3A, or more than twice that of a 6F8G (or 6SN7GT). The Glenn OTL can easily handle this tube driving a pair of 6AS7G, but very few other amps can. Be careful out there....

It has been several years since I last listened to this tube. For now, I am too captivated by old globe triodes to be seriously tempted, but I will definitely keep this in mind as a tube I want to revisit sooner rather than later...

Ken, that makes the 6F8G look like a new born :gs1000smile:

You know, it might be interesting to try the VR102/BL63 as output tubes, similar to the 6BL7/6BX7. But unfortunately, they are quite expensive and the cost of purchasing 4 or 6 of these is more than my wallet can handle. lol :)

Yes, that would be a quite costly experiment.

Yup. I think so, although I don't have any thing else more powerful. I am enjoying the paring though, no complaint.
