Diamond version? What do they have that the stadard EAT don't have? How much $$ are they compared to the normal $300 EAT.

Hopefully my Tele and Amperex PCC88's will quench my thirst Otherwise EAT might be coming

Philippe, how does it sound vs the stk EH tubes?

When I had the ART, 10 tubes stopped me buying anything. 2 is a lot easier to manage.

Shane....i paid 114 euros each, and it is the best present which I made for my GAT.... dead quiet tubes with beautiful soundstage and transparency, for me NOS quality without the downsides, i had a bad experience recently with a Mullard Holland CV2492 in my ET250s....I believed that my speakers had exploded...
Tolerances and the selection is, I suppose, even stricter for the version diamond

The EAT ECC88 is a special quality double triode. The tube satisfies the specifications in accordance with MIL-E-1/1J168 (NAVY) from 18.6.1958.

Tight tolerances: In these tubes the tolerance of electrical ratings are reduced in comparision with standard tubes.

Vibration and shock proof: The tube withstands accelerationns of 2,5 g at 50Hz for lenghty periods and momentary shocks of 500g for short periods.

Cathode free from Interface: The cathode establishes no interface even in case where the heated tube is operated without plate current over lenghty periods.

I took a look at their website and the ECC88 tube is listed as their "Cool Valve" EAT ECC88 Cool Valve | Euro Audio Team while their KT-88 is described as the "Diamond Valve" EAT KT88 Diamond Valve | Euro Audio Team

So, I'm not sure if they do have a Diamond version of the ECC88, at least according to their web site.

Effectively it is not mentioned on their site but we have here an offer for two versions: diamond 150-160 euro selected 100-120 euro

Eat, ECC 88 Diamond / Válvulas / Válvulas / SUPERSONIDO
Eat, ECC 88 Selected / Válvulas / Válvulas / SUPERSONIDO

Thank you, Philippe. I was unaware of the difference in gradings for the two tubes.

[Rafale]

my pleasure Joe, I have asked my seller about the Diamond version data sheet

The EAT 6922s here are expensive...$225 each at Music Direct. I would need to spend $900 on tubes just for my Premier 17...
