Need advice for my Jolida 302BRC

Martyw -
I've owned a JoLida 502B since 2001. I assume at least some of what I did will benefit your 302. Absolutely - upgrading the stock tubes is a place to start. I went to various KT88s in place of the Sovtek 6550s. Not sure what the 302B comes with stock. Talk to the folk at the TubeStore to get some ideas. I also upgraded the power cord and put in a HiFi Tuning Fuse. All these changes made a positive difference. My system is posted under Budget-minded so you will find additional details there. I recommend trying some of Herbie's AudioLab "Tenderfeet" underneath your amp. I found placement on a cutting board and better isolation seemed to tighten up the bass. Response Audio is another modder/upgrader to consider. Hope this helps.

If you haven't seen this; a starting point...

Good luck!

I have a modified 302b from www.hotrodaudiomods.com that i absolutely love.

I had one of these and it sounded great. Here is what I did: I got more bang for my buck by upgrading the stock 12AX7's and the 12AT7 (I think)tubes with amperex or mullards first. Then I upgraded the stock power tubes (El34's) with Mullard reissues (bigger soundstage but the reissues had reliability issues so I was using the stock powertubes while looking for a deal or real Mullards when I was forced to sell the amp. I used this amp with Spendor small floorstanding speakers and I found it very enjoyable and non-fatiguing to listen to.
