Elrog 300b vs we300b

@johnnycopy Thanks for the picture, those not the Psvane Acme. Just don't want the Acme to get bad rep, absolutely wonderful in my 300B amps.

Psvane manufactures different quality levels of tubes. The ACME is their uppermost tier for the 300b.

i noticed the acmes look completely different and more robust  The price, I am sure, reflects the difference in quality vs the pair I had.

The best 300b tubes are expensive. Their better sound quality and reliability are justification. If you have a high quality 300b amplifier and audio audio system, it’s the right way to go. I would not hinder a good amp with lower tier 300b tubes.

In an earlier post I mentioned I had owned the EML XLS tubes for 7 or 8 years. I came across an old post of mine regarding 300b choices. At the time I made that post I had owned the EML tubes for about six months, so early spring 2013. I still have those tubes and they still sound terrific! They tested strong 6 months ago on my friend’s Amplitrex tube tester. My how time flies.😊

Rlowe,
It’s hard to say, I used the Shuguang BT heavily for 2 1/2 years prior to getting the Takatsuki 1 1/2 years ago. The BTs are still very usable presently. I have the AVVT 32b (300b) which the Manufacturer said is a 40, 000 hour tube! I also have the EML XLS which shares a similar design and pedigree so who really knows?
