I’ve tried a lot of different tubes on my Reisong a10. But I always come back to the PSvane EL34b. These tubes are superbly musical and rich in sound. I’ve listened to songs on these tubes that I’ve listened for decades on a quality solid state integrated amp. But with these tubes I’ve heard warm notes that my other amp couldn’t pick up. I’m a huge fan of these tubes. Gotta buy some more
I just received my shuguang EL34-B yesterday, it sounds amazing! EL34-B is a beam tetrode fully compatible with original EL34 which is a true pentode. So compare it with original EL34 is not fair.
I'd guess one could automate 95% of all necessary steps with 2 roundtables having enough 6-axis robots for manipulations and spot-welding. By that approach its mostly a software designed machine, one could do every possible and impossible tube on a single machine.
@@markusweissenbock6337 How many vacuum tubes do you think retail every single day anywhere in the world? The fact its probably 5 digits is why this is still not automated.
Watching this I was kind of surprised that modern tubes actually seem to rely on human assembly to a much higher degree than they did at the peak of vacuum tube/valve production in the mid-sixties. This is pretty clearly illustrated in this documentary about the legendary Mullard company, at or near the height of its production capacity: th-cam.com/video/-GgWIlvyEL8/w-d-xo.html
I don't think that the actual assembly of the grids, cathodes, and plates to the mica spacers has ever been done by machine. Tubes have always involved a fair amount of skilled hand work. The parts to make them can all be stamped out by fully automated machines, but nobody has ever built robots that assemble those parts into a completed tube structure.
Were the Shuguang EL34's supposed to be a copy of the Matsushita EL34's. The plates of the Shuguangs look almost identical to their Japanese counterparts.
Thankyou for making our tubes, lovely ladies!
Thanks for your work, which allows me to have a lot of fun with music

This is the Shuguang EL34B, Psvane is rebranding it.
How much?
I thought I heard Dave friedman say the Shuguang EL34B has reliability problems
Pretty labor intensive. Didnt think it would be.
The Shugs are phenomenal tubes for early breakup and classic EL34 growl.
in my opinion, I will place the name of the operator builder on the glass they deserve credit
شكرا لك هكذا كان الزمن الجميل والاعمال الرائعة

Interesting stuff
The funny thing is that by the 1950s all of this stuff was highly automated with far less manual assembly than is shown here :P
The ´´Funny´´ thing is that it is not profitable to manufacture these tubes automated since they dont need to produce high numbers.
@@NinoJoel Ironically, automated production would actually improve quality. This is why tubes from the 50's were the best ever made.

Do they have plans of reopening the plant that burned in 2019?

I agree. I've watched the famous Mullard video too and there was a lot more machinery used in the manufacturing.
@@pstreetblues Which is probably why they are roughly 5x more reliable. If Mrs Ping is having a bad day..

Nice video

No boring music please
Too bad two pairs of shuguangs blew up the grid resistors on my marshall clone
