Jeff Rowland Model 8 - questions

I just bought one of these. I got a great deal and couldn't turn it down. It looks nice, but how does it perform? Does anyone have some good (or bad) information regarding this amp?
It is an early unit, and have never been upgraded. I have read that the earlier designs used choke input, and 320000 uf caps (thats inside mine). Then some modifications were done with the psu. The chokes were gone, and the caps now was 640000 uf.
How much better will it be if I perform a stage 1 upgrade? or stage 3?
Are there any recommendations to preamps? Of course JR will fit well, but I want to use a valve pre (with remote).

Hope anyone are familiar with this.
Best Regards

At last someone responded to my thread :-)
Thank you very much. My JR model 8 is up and running beautifully. It is one brute of an amp.
It is playing extremely well, however it is getting pretty warm when playeing for long periods of time. But if I remove the top, the amp doesn't get warm at all. I actually I prefer the sound with the top off... Why is that?
However the "warm-up time"
I notice that JRDG changed the top-plate for the 8 model when upgrading to the 8T and newer.

That is very interesting Daveyf.
I will try to get a new top-plate for the amp.
Btw. my former message didn't turn out all that well it seems. What i wanted to say was that I think the amp needs at least 6 hours warm up, before it performs best.
Anyone notice that?

Best Regards
