My Saga concludes?
I returned to work today after a week long vacation, and discovered that my YBA 200 was back from being repaired, upgraded to 200-2 specs, and biased for the KT88's I sent with it.
A few observations.
-It came to me in a much better box and packaging than the packaging I had sent it in. I will definatley be saving the packaging in case I have to mail this or any other large amplifier.
-I had sent it with a set of JJ KT88's. The amp was returned with the KT88's in their boxes, and the boxes packed inside the amp cavity with the rest of the cavity filled with bubble wrap and brown paper! Perhaps they saw the pictures posted on this thread of broken tubes?
-I had not requested it, and they did not mention it when they laid out charges, but they changed out the phase inverter JJ ECC82 (12AU7) with an electro harmonix version, and sent me the JJ tube in the EH box. I'm not sure if it is broken or just not "spec" but it was a nice touch.
So how'd it all turn out....
I installed the tubes per Eurotubes instructions (contact cleaner, etc.), hooked it up to my carving 8x10 and fired it up. There was one ominous pop when I finally got up the nerve to flip off the standby switch. I turned up my bass, plucked a string and then...NOTHING!!!
Then I realized I had plugged my instrument into the Tuner Output and I adjusted the cable accordingly.
It sounded wonderfull! Deep, full, loud, and quite clear (not perfectly clear, it's still a tube amp after all). With the Eurotubes Low Gain kit ("JJ KT88's for power but with two ECC81's ( 12AT7's )to replace the 12AX7's..." ) It sounds really full, and I can actually crank it past 5 without getting all that annoying (IMHO) disortion. The tone is much deeper and clearer than it ever was with the 6550's, even markedly better than when I ran 6550's with an ECC81 in the V1 position.
They seem to have biased the amp well, though I have no real way of knowing at this point. One of the power tubes had an "e" written on it on a piece of tape. I'm not sure why, but evidently they did at least take the tubes out of their boxes, presumably to bias it.
The bass I played through it was my Darkstarred T-40. It's a very versatile bass, so I was able to try out my usually woofy tone, and various spankier tones that aren't usually my preference. The amp sounded good for all of them. I find myself running High, Mid and Range at 5, with Low at 6. Resonance seems to be pretty useless, and I run it at 0, but I actually do like the Scoop knob now and then to "warm" up the sound. It definately gets the good warm tube sound that I was looking to achieve for playing with my current (country) band.
Overall, I'm pretty happy. I've spent more than I should have on this amp (see my earlier post for the figures), and I think the original fixed bias design of the 200 model is flawed, but I got:
-repair
-spec upgrade
-ECC82
-bias
-and return shipping
for $149, so I believe Traynor definately did right by me.
Only time will tell regarding the future reliability, but I am happy with the amp now and with the way Traynor treated me. It's not a vintage Ampeg (not that I could afford one anyway), but it sounds great, and barring any future unreliability I'll be holding on to this amp for at least a few years.
Thanks Traynor and Eurotubes, both of whom helped me out and gave me personal attention through this trying process.
