I disagree , Differences in tubes can be very noticeable.
A perfect example is a Telefunken 12AX7 vs Mullard 12AX7 is Very noticeable. I have tried many 6SN7 and found very few to have any decent bass. That was verified by Andy of Vintage Tube Services.
The only Vintage 6SN7 with good Bass is the Ken Rads ,but 90 % are Microphonic, or another with Bass is Tung Sol Black Plates(not sure of the year). The Sylvania 6SN7 has great Mids and highs, but is lacking in Bass. i have not tried New Production 6SN7s
Call Andy 616-454-3467
. tell him your amp . He can help, i promise. Maybe tell him which tubes in which spots V1.V2, V3 ..etc.
Let us know how it turns out
