TAD KT88 Redbase Valve's

Are you aware of losing the  EL34 mid/highs that the KT88 will not have?

The KT88 might be more dynamic/have more bass, but the EL34 magic will be gone-not in a bad way, just different.

KT77 will have more bass but retain the EL34 mids/highs.

Longtime PL user here. I have tried all, but use none of the above.

Hi tablejockey

Thanks for getting back, yes I am aware of not having the mid/highs on the KT88's , I will keep my EL34's but I fancy trying out the KT88's.

What tubes have you tried and liked in your Primaluna ?

PL HP user- over the years, I’ve settled for NOS 6l6G.

Note that it is NOT similar to the current, 6l6GC type.

6L6G type(pre 70’s) were a lower operating voltage tube.

A compromise of KT88 bass with a "close enough" EL34 mid/high’s

Still "reasonably" priced for a genuine NOS power tube.

Edit- "Genuine" NOS can be a dice roll relating to pedigree. Many listings are "pulls" disguised as NOS. I've had good luck with Brent Jesse.

I have been using their A-selected blue bottle EL34's in my EVO 400 power amp and love them. I too was thinking of trying a set of their KT88's. Pricey though. They only recently started selling the EL 34's and KT88's again after supply chain problems.
