When were the best tube amps made?

Would be really interested to hear from an engineer and tube amp builder today who has seen and heard many generations of amps.

@earthbound For the record, you did if you read this thread.

What kind of power supply capacitors did Western Electric use in 59A amplifier? I'm not sure it was already the mass production of electrolytic capacitor then.

@alexberger There were electrolytic capacitors in common production prior to WW2- by the early 1930s (the time of this amp) they were sealed aluminum cans that had all the wires exiting a single central mounting cylinder on the bottom of the part. The cylinder was threaded so the part was held in place by a single large nut. The internals of these things was frightful; electrolyte filled, with metal plate not unlike what you see in a vacuum tube supported in space. When I used to restore antique radios I would open these things up and install the replacement cap inside. From what I've seen of WE though they didn't use such parts. 

Thanks atmashere. I read some in the beginning and a couple towards the end. I will go back and reread the entire thread. Have a good weekend. 👍

I recently purchased a Roma el34 push pull as my first tube amp. I’m on the Decware list and purchased the Roma as a temporary amp. I owned a ss Rotel amp and preamp, Velodyne sub and used both AR10’s and B&W speakers for 25 years. Had the Roma going through some Zu Audio Soul Sipremes and it sounded great. Speakers induced ear fatigue so I’ve since gone to Audio Note e/lx’s. I couldn’t wait for Decware so I purchased an Aric Audio Custom 300b PSET amp. Hand made, point to point, hand made transformer which is a completely separate 60lbs unit, host of upgrades and no circuit boards. It can’t even be compared to what I used to listen to, and I loved those old AR speakers. Not saying there wasn’t great stuff back in the day, just thAt there’s great stuff being made now. All my vintage listening friends, old amps and speakers of good to very good quality, are really impressed with the sound. So good news. There’s great sound to be had today if you’re willing and able to be patient and spend a few bucks. 
Also, having read a ton on tubes the last 6 months, I came across an interesting article on the Western Electrics if I’m not mistaken. They newer owner was able to procure the original metal supply used in the old tubes. The process and significance is explained in the article. Very interesting. 

KrisKringle 3000B amps are made in the North Pole!  Truly outstanding!
