I always wanted one for nostalgia sake. I haven't heard one in years. If it is fully functional 200 is worth a shot.

The sun and fisher gear are real winners. You can't beat a good 2a3 amp.

What do you think about the RCA classic dual plates versus modern production mono plates? I've tried the EH, Sovtek, and a few others. I love the history and the quality of RCA 2A3 tubes I have a bunch of them.

This is a PWK design that was found in the archives circa 1946. There were some modifications but nothing that took away from the overall design. Parts have improved. Pretty interesting. There was also a phono stage found but that is for another day...

We are allowed to support the museum through the same process as everyone else. I support every fundraiser of the museum. I purchase from our visitor center gift shop when in Hope, online store, brick campaign, auctions, and also buy tickets to all our events whether I can make attend or not. I don't see a problem.. I would think it more strange if we didn't put our money where our mouth is. The museum is not rich and needs all the help it can get. We have a new free fundraising platform for the museum that includes a digital ticket system and auction system that we have been testing. If it works out this all our processes will be much more streamlined. The feature I like best is the ability to do online streaming of classes and events from Hope. The hard part will be getting a stable connection to do this. This will be part of the testing. To everyone who came to Hope or supported the museum through buying from our giftshops or tickets or campaigns thank you so much for all your support. The museum would not exist without you... https://boardsource.org/resources/personal-contributions/

I was going to do the same thing but you did such a great job there isn't anything left to say. Thank you so much for coming down. Thank you so much for your support of the museum. It is people like you that keep the museum going. You rock. Thank you!

Thank you Mark for coming all the way to Hope and for your help and time. It was great to see you again. We have been coming to these events for years now. I think we met in 2007? 2004? For those of you with poor comments, I challenge you to work with a nonprofit any nonprofit. It is hard work buy a few people who do it to further a cause they care about. We donate hundreds of hours a year. We aren't perfect but we love our mission and what we do. BTW I bought tickets as well and I would have done the same as Bill. I am also a paying member of the museum PWK started so many years ago.

Bill you are a true gentleman. The museum is so thankful and this is much needed. It was great to see you again. A few pics.

I don't know if my friend wants me to post it if he says yes I will post here. The curves we saw for the 6J11 turned out a bit different from what we were seeing in the amplifier. It is still being dialed in but so far very stable. Compactrons are cheap and still plentiful.

Conpatron was the last in tube design. We just used all compactron tubes in this build. They were tv tubes sweep tubes. They are cheap and quite good. Here is a good article on them.. https://www.junkbox.com/electronics/CompactronTubesIndex.shtml

80% complete all compactron SET amplifier which should end up around 5-10 wpc. 6HJ5 wired as a triodepower tube, 6J11 driver, and two 6ax3 rectifiers. This thing is so heavy. This will have side rails and a front plate. The is the HF amplifier. The LF is yet to come but it will all be mounted in a 5ft ham radio cabinet. An ode to ham radio craftsman ship... Still a few small issues to iron out but fun build. Thanks to my friend Chris for all the deisgn work. I am but a solder monkey...

Sorry for the delay I use pink noise, then i use a sweep, and then I listen finish by ear.

I use a an spl meter while I play white noise through the system and adjust the crossover gain controls till they are the same switching between amps. I have them marked with tape in case I move them. Currently building amplifiers specifically for them the HF will be an all compactron SET amp 5-8wpc with a 6HJ5 not sure what will be LF.

I got a Jelco 12 for my Garrard. I was lucky to find one that wasn't in a studio or dj booth. If you want to build your own plinth there are tons of cool tables out there.

@Travis In Austin I was thinking horn loaded a$$? It was a marketing sales team shirt and I do not know the significance. That being said I could not help but put it on a shirt...
