Springbok1, I would talk to both Jolida themselves and maybe to the Parts Connection about the triode conversion. I once heard a Jolida 302A converted to triode operation (glorious sound), and I am not sure if the guy did it himself, had Jolida do it, or Jolida referred him to someone...
I am happy you have switched to the KT88 tubes, as I like them sooooooooooo much more than 6550s. A lot easier to listen to; more tubey.
I am wondering if the "upgraded" Jolida is the source of your discontent. I have nothing at all against UnderwoodWally, in fact he seems to be one of the best dealers on Audiogon. Just that if you read one of my posts above, you will notice that I SPECIFICALLY mentioned to look for a non - modded Jolida 202.
In my experience, most of the modded equipment that I have heard is not exactly to my liking. Yes, they upgrade parts, but does the end result represent better value than the starting point? Often, a lot of the mods (such as better caps, especially those made in California) can bleach or whiten out the sound of a component. This can destroy the easy to listen to nature of these mostly Chinese built components. Their endearing nature is that they sound musical, where they fall short is usually in resolution and refinement. I think a lot of the mods often rob Peter to pay Paul. Resolution and refinement go up, but musicality and their relaxed nature sometimes is lost.
I am of the opinion that at the price of the modded equipment, I'd rather move to the Carys, Granites, and Rogues of the world.
But, modded components are hot, hot, hot, so you figure most people like them a whole lot. Perhaps, I am the one who doesn't know what he's talking about...
