help needed from the 300b crowd!

Magnetmaz · 20th February 2003, 09:33 PM

Ok. I got my 300b amplifier.

Now : which brand of tube to buy?

Since this is my first set, and i'll probably bias them too hot and burn them out quick or something...i want to go with a lesser-cost brand... So WE is right out.

So : between Valve Art and ElectroHarmonix, who makes the better 300b ? ( i think these both go for about $40-50 each )

Are there better manufacturers that are in the same ballpark price range?

Hi,

For the record Electro-Harmonix does NOT manufacture any type of tube.

My vote would go to the Svetlana 300B, not overpriced as the WE and a close copy nonetheless.

Cheers,

Hello,

Here is another link for an equally interesting test about different 300Bs. By the way, there is no reason why you should "fry" your tubes, providing you take a few minutes to choose a proper bias/voltage setting. Your 300Bs should last long, very long. Enjoy!

Post a pic of your amp when you get it finished!

I have some of the EH 'Gold Grid' 300B's that I got a short while ago. They're not in a circuit yet so no comment on how they sound. If you hunt around, you can get them <i>much</i> cheaper than the MSRP.

I quite enjoyed the Valve Art 300Bs I had. I got them from Angela Instruments. I think they were the Angela branded ones.

Later I regretted keeping the Svetlanas in favor of the Valve Arts. The Svetlanas turned out to be weird and one has since failed, but that's my own fault. I bought them from someone selling them as factory new, but cheaply on eBay. I think they were rejects or seconds.

Jeff...

a lot of Svetlana's fail...
but if they last you past 6 months..they should keep you happy for quite a while.

Apparently there is something about the filament in the svets..heating up cooling down that breaks the filament as they contract and expand over the "thingies" that hold them in position.

Cheers,

Hi,

Just for experimenting you could buy a pair from this guy
kwtubes
his 300B's are only $25 and go for the more expensive stuff when you're satisfied with your measurements.

good luck
