Finished chassis prep work for the two OTLs I am working on.

Here is the one in Anthracite Grey.



Here is the one in Chromy Bronze.



Also did the machining of the power supply regulator heat sinks. PCBs are already done, so now just need to mount parts and wire them up. Got hit with a migraine today though, so will get back to it tomorrow.

Sweet!

Sorry to hear about the migraine, but I have certainly felt your pain. Suffered with them since I was a kid, and a couple different doctors told me (after doing a battery of tests) that they would become less frequent and eventually stop altogether as I got older. Seems they were right as I haven't had one in 5+ years. They never said exactly how old, just older....which I suppose I am.

I get them maybe once or twice a year, it's gotten less frequent as time has gone on. It's annoying, but since they occur so infrequently, I haven't seen a specialist about it. It's really only a major problem if it happens while I'm at work as I get an "aura" at the onset lasting around an hour and lose nearly half of my vision. This is not ideal in an emergency situation LOL.

Everyone is older, all the time, until a radical change happens. Doctors!

Today is the two year anniversary of starting this thread. Time has flown by, it's been quite the journey, thanks for everyone who has followed along. I thought it might be fun to go through the pictures I've taken over the last two years and post the ones I liked most. Here's what I found.

That's the best audio porn centerfold I've seen in a good while.

I haven't been following for all of the 2 years I don't think, but I've sure enjoyed the time I have spent here...and learned a lot too. Many, many thanks for sharing all that you do.

Really beautiful. You are glass, wire and metalworks artist.

Thank you! Obviously two of the pictured amplifiers are Glenn's, I like the photos

 

[Galapac]

You build great amps and also have an eye for great composition in your photos. That seems to go hand in hand in our hobby with a lot of folks.

Great pics. It has been fun following all of your builds and learned a lot too.

It sure does not seem like two years, but man, how time flies.

Hope your migraines settle down. I got my booster last week and I did not have any ill effects other than sore arm.
The first two shots put me down for a day each. I feel better getting the booster, since I have been seeing quite a bit of live music
and the protocol's seem to be all over the place for each venue.

If you would not have had to stop building for the public, which I do fully understand, I probably would have been a future buyer of something.

I really like the looks of your builds....old skool at its finest.

I hope your work is going well....seems to be that time of year again where the covid is the most severe.
Stay safe and thanks for all you do.

Thanks, Joe, time has flown by, work isn't going well but so it goes, the surge in Ohio is very bad. That booster really knocked me out, and it's expected the CDC will recommend additional boosters, not looking forward to that, but even if someone who is vaccinated gets a breakthrough case, the data shows the vaccine protects against severe illness and hospital admission. That is the real key, as our healthcare system is completely overburdened and cannot sustain this, something's gotta give! Pfizer has a new antiviral medication they think will reduce hospitalization rates, if people are willing to take it, that may help. But who knows, the future of inpatient healthcare is very uncertain right now, critical care healthcare workers are completely burnt out and leaving in droves, I'll just keep taking the beating and build some tube gear to keep occupied when I'm home!

 

[L0rdGwyn]

But anyway, got some time off coming up which will be nice. Won't get a lot done on the two Airmid OTLs until after the holidays, but will surely post progress when I get back to it. Also have some really rare globe MH4 triodes on the way to me from Billington that I'm pretty excited about also still considering throwing together that spud amplifier, started drafting a chassis for it.

Yep double vaccinated here, but still got a mild dose of Covid. Very thankful I had both vaccines and I'll be lining up for my booster in January. The medical workers are working wonders here. I lined up for only 20 mins for a walk in test. Tiny little tube stuck up my nostril and then I had the results late evening. First felt sick 8 days ago but almost back to my usual self now.

Aha - you are ordering British tubes from Martin, and I've just put in an order for some US tubes

Glad it was a mild case, that's pretty typical for someone who is vaccinated. Unfortunately there are vaccinated but immunosuppressed patients with breakthrough cases who don't fare well. Other than that, the vast majority of severe cases are unvaccinated.

There was a little note in their Christmas newsletter about having a quad of "balloon shape" MH4. These things are super rare, not cheap, but a song compared to what you might see them going for on eBay, so I bought them what US tubes did you buy? I haven't bought any tubes from Martin in a long while, mostly I am hoarding HY69 from anywhere I can find them for some crazy future amplifier.

Yes I saw that too and actually thought of your amps! Glad you got them. I ordered some Sylvania and RCA. I'll reveal which ones next year over on the The Reference Pentode and Beam Tetrode Thread.

I wonder why I do not receive their newsletter...
Bought tubes from them couple times in the past.
