6SN7 and 6SL7 tubes recomendations (Cayin A88T integrated)

Linlai E-6SN7 is excellent, transparent and dynamic. But it has a large bottle, there's a diagram with measurements on the website.

I have Cayin A88T, mk1 with 16 ohm taps/internal bias.

I switched from 6550 and prefer KT88's. Have you checked your bias?

I bought replacement 6sl7 from Brent Jesse, glad I chose him, he let me return the matched pair I bought and did NOT like the sound of.

6sl7wgt Sylvania military (picked so the would purposely look different than the adjacent and identically sized 6sn7s (that's how I blew one, put it in wrong socket)

he said: break them in for 60 hrs, still no like, return for full refund.

I found and love the sound of 6sl7gt general electric, side getter, cylindrical plates 

they sound just like the Cayin originals whatever they are.

I'm still using Cayin 6sn7's

Hi, thanks everyone for the replies.

Yes I checked the bias of my amp, and it was also serviced to check the inside regulation of the bias (some A88T have problems with that).

I currently use KT88 Genalex Gold Lions, said to be the best with this amp (?).

I wondered how they compare to Psvane KT88. I gave up switiching to 6550 which doesn't have to bring any advantage.

Regarding the 6SN7 and 6SL7, I will check the other topics. Linlai is quite new on the market, Psvane, Shuguang are more well-known and have more feed-backs on the web...

I had new Tung-sol 6SN7 and 6LN7's in my amp.  I purchased some NOS Tung-Sol Black plates from Brent Jessie with really good results.  It was definitely an upgrade.
