I just learn that there is a store there that carries the Oblivion amp and ZMF headphones, etc. https://www.beyondthemusicid.com/
So joining this cult, am I free to leave when I want to? Or is it a case of ''You can check in anytime but you can never leave".
Killer build sir!@Isaacc7
I usually don't post pics mid build but thought I'd make an exception here. Mainly to show Isaac of course.
This is the push pull version of Odyssey with manual grid bias. The four output sockets are in the back row and driver tubes at the front. Below each output tube socket you have a trimmer to adjust the negative grid voltage. The red measuring terminals is for external voltmeter to read that voltage. There's only one black terminal as it's just ground anyway.
In between each pair of output tubes there's a little toggle switch. Toggle to the left to measure the anode current of the left tube on the mA meter and toggle to the right to see the anode current of the right tube on the meter.
In the middle there's a panel voltmeter and below it is a trimmer. Here you adjust the B+ (also anode voltage). The range will be around 240V-400V.
The two large toggle switches are for the heaters. Up is 6.3V and down is 12.6V. One switch for driver tube sockets and one for output tube sockets.
Isaac, do you need me to label everything or can I leave it as is? I think the "clean" look would get destroyed as there would be lots of labels lol
Btw, this is the heaviest amp I've built to date! That Monolith PT is a beast! The amp weighs 26.5kg as it is now even without bottom cover and lots of components missing!
Looking awesome as always Tomas, looks like a beast, especially with those really beefy Transformers@Isaacc7

Hmmm............
FTFY.
Woo! Love the look! No need for labels, let’s keep it clean. Those are banana ports for reading the voltage right? Those monolithic Magnetics transformers are looking rather like monoliths Lol. Triliths? What does the back look like? That power transformer is big enough it could make sense to have it on a separate chassis. I prefer it all on one though. My preamp has separate chassis for the power supply and it’s a bit of a pain and I’m always worried about the proprietary umbilical cord failing me. You’re further along than I thought you’d be, it’s on the the first of the month!@Isaacc7

Yeah, that’s my situation too. When you love vintage tubes you usually can’t get matched sets.
Yeah, this is kind of a love letter to tube rolling lol. I fully anticipate this being my last push pull amp.
It's a love letter to tube rolling and a suicide letter to your wallet. But you are lucky to use mostly unknown types and this will help you a lot. I will definitely go to the 12.6V path on my next amplifier.
The OT transformers are rated at 30watts down to something ridiculous like 5hz. In theory they could do a lot more at normal musical frequencies. In the end, the power supply will limit the maximum power. Well, that and my ears lol. While I expect to be able to get something like 30 watts from GU50, KT88 and the like. In reality I really only need a handful of watts And so will never need that much. On the other hand, maybe now I’ll finally have enough power to get a pair of LS3/5A monitors with their 83db sensitivity…
Luckily(?!) I feel like I’m putting the final touches on my tube collection. And yeah, I have spent an unconscionable amount of money on them. I have so many now… Luckily for me I am addicted to relatively inexpensive tubes, or at least less expensive versions of expensive ones lol. I’m just putting the finishing touches on Mullard, Brimar and Fivre 12sl7 order. These tubes are a prime example of ones I wouldn’t spend the money on the 6v versions.
