Hi y'all,
Checking out the mods for the SVT some of the following questions
came up...
From the Tube Amp Book (4.1 ed, p. 278) and (Deluxe Revised ed, p132)
Discuss changing the the resistor values of R6 to 220K, R7 220K,
for use with a 12AX7 tube. However, both books show a change to
R-25 to 4.7K resistor?
The schematics show the R24 and R25 (4.1 ed, p. 345) and (Deluxe Revised ed, schematics, p14) to both be 47K as they connect to the p5 of the power tubes.
Did they over look this in both pubs or do you have to compensate
for the 12AX7 that much?
