Philco used a lot of Sylvania tubes. The 1929 and up nice mesh plate 27's branded Philco are Sylvania. But the Philco tubes I got are unlike any Sylvania I have seen.

Takezo, I also was quoted a similar figure, but in my case the price was for international shipping. Not sure why you were quoted 40$ for delivery within in the US.

Any thoughts about the TJ Full Music 274B tubes?

A recent 6moons review of a Yamamoto amp had a sidebar which showed the TJ FullMusic tube manufacturing facilities and from what I could tell, they have been in the business for a long time and make good quality tubes. I'm not sure if there is any difference between the Sophia branded tubes they make and their own TJ branded tubes.

yeah, $40 for shipping and handling... i guess ny to l.a. is kinda like international
shipping... lol... they're probably just trying to milk it for all it's worth
while the getting is good...
he mentioned that he recently had a rush order of the 274b and that
he had to order more than 15 tubes just to catch up to the demand...

anyways, from all that i could gather, and i may be mistaken, the tj full music
274b tubes are made in china by a well known tubemaker there and that all
of the sophia 274b, that includes both the standard and princess, are just
re-brands of the tj full music tube. sophia's electric wouldn't respond to my
inquiry several months ago but from what i've read, the internal construction
of the standard, princess and the tj full music are completely identical...
my guess is that the princess version are hand-picked for superior sonics from
the batch that sophia receives from china... i repeat this is just my guess.
the only way to find out for certain is to purchase all 3... but what's the point?
as long as the princess sound great i'd gladly pay the extra $15 for the better
performing tube from the same batch. saves us the trouble of having to buy
several to pick them out ourselves...

btw, the valveart 274b is a rebrand of the shuguang chinese version that
goes for aroung $10-$18 on some websites... i had one and it sounded decent...
but died on me after about 4 months of light playing... still not bad for the price.

PS: musicmind has kindly indicated, correctly, that TJ full music has another
version of the 274b, the N+, that is different in internal construction from the
princess and their N model. another choice to add to the mix...

What brand... Philips, Sylvania, other?

And... where can you buy them?

 

[jamato8]

I get most of my tubes off of Ebay but then I have been buying there for years and you have to know what to look for and questions to ask to get a good tube.

The two I just got are RCA nos. I find the amp does better with rectifier that draw 2 amps vs some of the tubes that draw 3 amps for the filament even though the amp is rated up to 3 amps. The 5V4 is a 3 amp and then there is a 274B n+ from China that pulls 4 amps.

I got a tube from ebay last week and the getter was gone. The tube looked fine and many people would have gone ahead and used it but the tube isn't any good. I contacted the seller because this is a bottom getter tube and might be easy to not realize the getter had been used up and he refunded my money. I explained what he needed to look for since he appeared to be new to tubes and he had located a bunch he wanted to sell. Sometimes the getter turns white and this is very observable but sometimes it dissipates slowly over time and thins and thins and then is gone and no more silver getter because the tube has gotten gassy by leaking in outside air or maybe it was that way in the beginning.

You had Jack mod the WA6 to Jamato's design right? How much did that cost?
