Tubes for VTL 7.5

12AU7s also reduce the gain a little. I ended up upgrading the the MkII preamp instead. A nice step above the original. The 12AU7s are a little soft in the use in the original 7.5.

Thanks for all the help!
I ended up with a matched pair of Telefunken ECC801S 12AT7 from Brent Jessee. WOW what a difference. I would of never thought that $400 could make this much difference. I have bought $5000 speaker cables that never made this much difference. Everything is just better from the Bass to the Highs. All the glare is gone....

I really can't believe that there is really a preamp better then the VTL 7.5 with the Telefunken tubes in it. I have had preamp costing twice as much and they never had the overall sound quality that the 7.5 has.

BTW Brent Jessee is awesome to deal with and he sells the real deal.

Mtdking,

I hope the 7.5 can handle the 12AT7 as it is setup for the 12AX7. You can use a 12AU7 but it changes the sound a little. But I would check w. VTL about the 12AT7. It might also be OK & sound amazing & just stick w. it.
