we had one guy swapping tubes behind a curtain so we did not know which tubes we were listening too. When the KRs run, to a person, we all were shocked by how much better they sounded.

Was each tube biased to its own optimum range when switched? If not, the difference may just be due to that which can also be done without changing tube if the amp has adjustable features.

I think that is also the reason that I feel the Gold EH300bs sound a little better. With a direct swap, all adjustments the same, they run about 10mA hotter than the regular EH300b.

Hi,


Psvane Hi-Fi series at $300
EH 300b at €270
EH 300b Gold at €310
Shuguang 300b at $320
JJ 300b at €400

check partsconnexion, EH 300b Gold at $170/matched pair

these sound acceprtable, but the glass is a bit thin and that makes them a bit more microphonic than usual!

These guys sell JJ300B's for a little less and looks like they thoroughly test them. It's the only brand they sell for new tubes.

I have four new TJ 300B with meshplate and 2,5 volt filaments for sale. Bought them a few years ago and never used them.

What a nice name for the thread! When I saw it first time I thought it is about making a poor man's 300B in garage.

Anatolyi is reminding me that I solved my "budget 300b" situation by using PSE 4P1L as output tubes. In comparison they're super-mega-budget!

Indeed!

As soon as I finish a couple of my current projects I am going to build a no-GNFB amp with 12x4P1L

Is there any reason that 300b's are so much more expensive than other tubes? Are they more difficult to produce? Or is it just their reputation and demand for them?

Sometimes you do get tubes that are difficult to produce. The development of what became the KT66 traces the story of how British manufacturers threw their hands up in despair at the task of making a workable beam tetrode and gave the job to the Americans, who said, "No problem."

The Chinese seem to say "no problem" to everything, and could easily flood the market with low-priced 300Bs, so the price probably reflects what the market will bear rather than manufacturing overhead.
