VA 350B sounds pretty good
03/30/13 at 21:30:34
 
So I did some overtime and sprung for a pair of the Valve Art 350B tubes for $40.00.

Sound pretty darn good.  Very big presence/soundstage, airy maybe less bass then the 40's RCA 6v6G St i had in there.

My reference LP is Zappa's Apostrophe

The pins do seem thicker than the other power tubes like Reflektor and the RCA's.  Hope it doesn't cause any loose sockets.

I recall buying some Chinese adapters that had that 8 pin socket. The pins on those adapters were fat and I also wondered whether they would cause undue wear. Maybe the VA 350B will be good for acoustic material where you need that big sound-stage. Then a good 6L6 will expand the sound-stage measurably.

Well after a few days of the VA 350B i missed the punch the RCA 6v6g st's from the 40's have.  swapped back out.

So..... keep an eye on the classifieds  i might send them on.

They sounded nice but lacked that punch in the bass.  Very airy open sound but.....

IMHO, you need to get them fully burned in before deciding to sell them.
A few days use is not enough.

I have used both the VA 350B (still have them and will sell for $25.00/pair) and the 1940's RCA 6V6 ST.

After a lot more tube rolling, the Mazda 6v6 GT was the clear winner (a Brent Jessee recommendation)

The VA 350B is very good and a bargain (the VA 350B is far superior to the stock Tung-Sol 6v6 GT).

The Mazda 6V6GT tubes are Organic, Smooth, Lifelike and provide the most Detail (with a very light touch, not harsh at all, but the amount of new detail is amazing).



From Brent Jessee's website:

6V6GT Mazda France made greyglass, military boxes, 1957 dated
New Old Stock original box.

A very nice 6V6GT, not often found in the USA. Blackplate and greyglass, Mazda label all with 1957 date codes. These Mazda made tubes are similar to Pope, Amperex and other premium brands.

I keep preferring my G ST (1940's) RCA 6V6's in my Mini Torii. These, coupled with the right 12AT7 (i.e., Brimar) makes for a great synergistic match.

Having said that, I'm still looking for better options ... Currently Mazda's are out of stock, so I'm still on the look-out for alternatives. Same with the preamp tubes. My last 12AU7 black plate RCA's did not make it. Not even close to the Brimar (12AT7's). Same with the 6414's.

I believe unless it is a super special preamp tube, the 12AU7 doesn't cut it in my system, too dark, mellow and warm ... I prefer the kick out of a good 12AT7 or anything close to that spec. Need to find them both (6V6 and 12AT7 alternatives) though ...
