6505 Plus - Preamp Tube Configuration....help please

Post by davidvignola » Tue Jun 13, 2017 12:35 pm

I have a 2015 6505+ head and I am upgrading the tubes. My question is on the preamp tubes, when you take off the cover and are looking at the tubes from the back of the head are the order of tubes from left to right

V1, V2, V3, V4, V5, V6

I know on some amps they are not in order that way and I want to make sure I put the replacement tubes in the proper slot if that makes sense? I purchased a set from "Dougs Tubes" and here is their recommendation

V1 - Tung-Sol 12AX7

V2 - JJ ECC83

V3 - Ruby 7025SS HG

V4 - Ruby 7025SS HG

V5 - Ruby 7025SS HG

V6 - Sovtek 12AX7 LPS

I want to make sure I get these physically in the correct spot.....Thank you in advance

I believe the layout is as follows, looking at the back of the amp left to right:

V4-V3-V5-V2-V1-V6

If this wrong, please correct me.

That looks correct to me.
