Have this amp and before I take it all apart once again I thought I'd ask the community first. Amp was NIB (NOS - S/N 233 a nice find) two years ago, and I just tried it on 10m today to go after the

My feeble brain seems to think your amp was made by Viewstar (Canada ?) and B&W stuck their name on it. Worth a Google. Sent from my iPad _______________________________________________ Amps mailing

I bought a Viewstar PT-2500A for my father and he still uses it. I like the "instant on", 100W drive gets around 1400 out and down the road it'll come to me & I'll add on a remote QSK unit. Its a nic

I think we got off the rail a bit with respect to the history of the PT-2500A which has been discussed elsewhere at length. While that is interesting, I need to get back the primary objective - What

Both references suggest adding a single 133pf (100pf & 33pf in parallel) cap with a coil of 6t of 18ga wire, loose spaced (about 5/8" long ) on .500" diameter. However, this yields a C-L only solutio

Perhaps they suggested the C1-L solution for the input tuning on 10m because the input capacitance of the tube/s is regarded as sufficient for C2 of the Pi circuit on that band. 73, Alek. VK6APK What
