Anyone Using Longer Plate JJ 12ax7/ecc803?

Yep, seller says ecc803 not ecc83.  I am wondering how close to the description these sound?

The JJ Electronic ECC803 is a high performance, long plate version of the ECC83 / 12AX7. Like all JJ preamp tubes, these are built into a rugged package using the spiral filament and robust plate structure resulting in low microphonics and high reliability. The long plate version of this tube differs from the standard version with its stronger and fuller sound which offers a wider and more balanced frequency response. This tube ranges from deep rich lows to pristine highs covering a spectrum of harmonically dynamic mids along the way. This tube is an excellent choice for any guitar amp and perfect for studio and Hi-Fi equipment as well. This tube will work in any 12AX7 or ECC83 position.

I have a pair of the SKU: T-12AX7-GOLD-JJ  12ax7 that I got from Antique Electronic Supply and they are GREAT sounding tubes for guitar!  In a silver face Vibro Champ, they totally give it a tweed tone/tweed sounding breakup, I'm wondering how the longer plate tubes might sound compared with these?

I stopped buying JJ's.  I don't trust them anymore. Too much failure, too often. I switched back to sovteks.. ok not exciting sounding, but they're very reliable.

I’ve used a lot of the ECC83s over the years with good results, not so good on the 803s. They tend to be on the microphonic side. If you haven’t already you might try the Tung Sol. I like them in V1. The TS tend to be warmer than the JJ.

Wow, thought you were plugging this tube for JJ..... Sure you don't work for a JJ vendor?

Some people like them, some people don't.  At ~$16 for the non-gold-plate variety, you should just buy a few & form an opinion.

No extra magic (just extra $$) for the gold-pin tubes.  And long-plates have a greater possibility of microphonics (which is why tube makers switched from longer plates to shorter plates in the 50s and 60s).
