Default Re: Restaurare Leak III ST Refurbishing

I finished the u-Tracer, so I can scheck also the tubes.
The result was:
V1(ecc88) verry good, both sections more tha 100%
V2(ecc85) one section 60% and the ather 50%
V3(ecf80) accetable both sections but pentode was 70%
V4(ef80) 60%
V5(ecf80) accetable both sections but pentode was 70%
V6(em84) ok
V7(ez80)80% both diodes
As the stereo decoder was not a big thing I was listening first in mono from the cathode folower out and then using the external Fisher MPX 100 using a direct conection from the tuner mpx out prior to C51...this one was better than the germanium decoder but still lack of "life"
Shall I replace the tubes first?
