Tubes changed, another step forward, next small step fuse change and finally feedback resistors change

First step done! Replaced the trimmers and the new ones fit perfectly! Once all the electrolytics have been replaced, the 4 power supply ones are very difficult to remove, however they are all of good quality and apart from one they are still within specifications. At the moment I have still left the old tubes so as not to change too many variables together, however the sound has already improved! Here are the trimmers https://www.digikey.it/it/products/detail/bourns-inc/3339H-1-202LF/1060414 and the power caps https://www.digikey.it/it/products/detail/epcos-tdk-electronics/B43547A9477M000/4943328 ATTENTION: the power supply caps do not adapt immediately to the circuit, a rheophore must be lengthened to allow offset assembly.

Time for restoration is coming...

R21, R22 and R23 together with R5 make up a divider and the total gain is determined by (R21 + R22 + R23) / R5

Hi, my first post here, I am the new owner of a T1, I am preparing a restyling of the trimmers, capacitors and resistors, regarding R31-34 I have R31-R32 = 7.5K R33-R34 = 15K maybe they have been changed by the previous owner? Someone has already changed the cables and rca for sure and who knows what else ... Have any of you ever replaced the feedback resistors and capacitors?
