Need Some Educated Advice...For a Newbie Tuber

I don't own a Jolida amp but all the tube amps I have owned have benefited from certain special kindnesses.

The first is to get them down to the floor if you can. Bass gets better. Next is footers. Some swear by brass cones or spikes, others by soft footers, I use brass cones myself, bought from EdenSound. You can put the footers between the amp and the floor or you can spring for a rock maple platform and put the amp with its footers on that.

Herbie's tube dampers, first on the drivers, then the output tubes, come next.

Last comes a premium power cord.

Now I purposely didn't mention NOS tubes. The small driver tubes make a lot of difference, but if you're a NOS beginner, it's a jungle out there. Your 12AX7s are among the most expensive. 12AT7s are a little easier on the wallet. You can look for NOS output tubes if you like but you need 8 of them -- a pretty penny if you must have, for example, vintage Mullards.

I'd start with the footers -- look into brass cones or maybe Herbie's Iso-cups -- and meantime do some research on the NOS tube side.

Have fun !

Spin some LPs

I owned that adcom amp many years ago...very harsh sounding but powerful...if you haven't done so run a dedicated 20 amp line for your gear. tube gear is susceptible to vibration so use good isolation techniques........footers, decent rack etc.....if you have not treated your room you should do so since the "shrillness" might just be your room acoustics.....after all that's done I'd experiment with tube rolling to see if you can get the exact sound you want...the 34 tube is pretty inexpensive and there are lots of options.

The above notes on the minor tweaks initially listed are sure good ones. I too would begin there.

Cabling thereafter. Interconnects mainly.

Then a good rack.

Then… what ever and where ever you wiah to spend some dough.
