EL34 upgrade
Yes output tubes have a break in period. With 6550's is usually 10-30 hrs. Depends on the amp and the tube. 
EL34 upgrade
I agree. The Winged C's are excellent for the price. I just got done recapping 2 Marantz 8B's and put 2) quads of the Chinese EL-34's in. Seem to be very very good and strapped the amps are putting out 77Wrms across 8 ohms. Can't beat that.

Mystery 30 Minute Sound Degradation
Teflon caps are notorious for taking forever to break in. I would suggest you wait till you have at least 100hrs. break in on the caps before you start changing anything in your system. I'm guessing it's just the coupling caps acting weird. 
Why shutting down?
It really depends on what the protection circuit is sensing. If it's D.C. at the output, it could be a leaky output transistor. It could be as simple as the protection circuit is set overly sensitive. If you are using very old speakers with foam s...

I totally agree with Pdreher. Even LS-3/5A's would work, Silverlines etc.. 
Sonic improvement with Threshold FET 9 refurb?
The SP-11 although an older design is also a very different design from the SP-14.... 
Klyne SK-2
I believe the Klyne has little switches under it's top cover for adjusting input impedance to match the cartridge. I always ran MC cartridges wide open i.e. 47K unless there was a reason not to. 
Sonic improvement with Threshold FET 9 refurb?
I believe the SP-14 is somewhat similar to the SP-9. Both of these units had crosstalk issues. As frequency went up, crosstalk went up. This caused a problem with the image to some extent. It manifested itself as a whitish curtain between instrume... 
Amp blowing right channel fuse?
The first question would be: is this a line fuse, or a B+/B- rail fuse, or a speaker fuse?
