I am looking for some advice regarding which preamp tubes i should put in my mKIV.

i have a ton of jj, some mullards, some tungsol, and some EHX.

what would you recommend and where? would it be smart to throw a 5751 or a 12at7 in the PI?

what would you do? (i refuse to spend more than $20 on a preamp tube FWIW).

try some different configurations.
yeah I'd try a 5751 in V1 and the PI

Well, what is your initial impression of the amp as it stands? Too bright? Too dark? Lacking presence? Too shrill? Too thick? Too thin? Too fizzy? Not fizzy enough? And so forth. I personally set up most of my amps with a Tung-Sol in the V1 feeding into a JJ/Tesla in the V2 or whatever positions are designated for the gain channels.

I like the Sovtek LPS in the Phase Inverter position.

You're the chap that has enough tubes to last you until JJ's become rarity, right? Try them all and see. c:

For PI a Sovtek 12AX7 LPS is often suggested. I am not sure why. I have one in the PI spot in the AC30, sounds fine to me.

I threw a jj 5751in V1. Then a tung-sol 12AX7 in V2, and the others just got jj 12AX7's, and I threw a jj 12AT7 in the PI.

The key players were the 5751 in V1, and the tung-sol in V2. That is what made the biggest difference.

Now it's a totally different amp. Less fizz, and less mud. Clean channel is infinitely better too. The tubes that were in there were probably 10+ years old. If not 20.I went through the whole amp and cleaned the tube sockets and jacks. I will get to the pots another time.

Ovrall I am very happy.

Keep the New Sensor stuff (Mullard, TungSol, EHX, etc) away from anything with a cathode follower. That would be the FX send and probably the tone stack. They'll die quickly.

You have to consult the schematic. If the output of the tube is on the cathode, then it's a cathode follower.
