Jolida 302 convrted to a 502?


I have a Jolida 302 that came trashed from shipping. I have it working fine but I'd like to up the output. The pro shops offer an upgrade that does little more than change 4 resitors and 4 tubes. Of course they are not forthcomming with that info. Can any one walk me through this? I posted once before but got no responce.

Thanks guys, hopefully someone will give me a walk through. I am running a 94db single driver speaker set up I made myself. There better than any over the counter stuff I've tried to date, with the exception of the DAli stuff. By the by, I listen to everything from Django Reinhardt to the Grateful Dead.
Thanks for the feedback Ponterio22554.
Looks like you want a walk-thru on how to change EL34 ckts to a KT88 ckt. Right?
Looks like you are handy too, which is good.
Here's what you can do to help yourself: call up JoLida & ask for the 302A or B ckt schematic. They are pretty good in honouring your request. How do I know? 'cuz I called them up & requested a 502A ckt schematic & they mailed it to me!
Once you get the 302A/B ckt schematic let me know, I can fax you the 502A ckt.
Compare the 2 & modify the 302 to a 502 i.e. convert EL34 to KT88.
Thanks, I have the schematic. Its the same with some exceptions, none of which I can recognized. Please e-mail me and with your generous help I may get through this. I'm at ponterio22553@yahoo.com.
well, I tried to email you off-line & I got this error message:-

554 delivery error: dd this user doesn't have a yahoo.com account (ponterio22553@yahoo.com)

What gives??
