You are absolutely correct.

Incidentally I did come across a few references to this tube made by Tesla Vrsovice while trawling the net.

What's scary is that I also read someone claiming the KT88 Teslovak as offered by the Pentalabs people is made in China.
The market is starting to become really very confusing...

Hmmm, just revisited the PL page for the KT88, they actually say themselves it's made in China....

I found a source that carries the real TESLA one but at Euro 90 a piece that's not exactly cheap.
The internal reference at the factory is RE 40 AK.

I actually have the datasheet in PDF format, if anyone wants a copy, e-mail me.

Hi Frank.......snap......Your'e quite correct RE40AK as orig tube....and yes they aren't cheap...the tubes have also scratched ID's inside on the A plate....I blow brass and use these for studio and stage work. This is the only newest made 88 variant I've used that comes (near orig) MOV spec. At 600V, it blows the chaff away from the grain.
As for manufacturers I suppose there's something to be said if the establishment has ISO9000 conformity ? The trend is gradually looking in that direction.
Certainly not from a far eastern JUNK fabrik. There's a commercial racket going on where so-called good brand tubes are be made at cheapest facilities, with scrouge wimpy QC. (quality control)caveat emptor!

I've known about the Pentalabs.......jury's out on this one...From my experience, when MOV gave up UK manufacturing GL 88's and farmed the plant out to China......the result was wimpy unreliable tubes..that's written all over..........I'm staying caged up with the Lions however, pricy they are. However Pentalabs may issue a <home-made pledge promise> ????

Viva 88's.
