Jolida 502B correct tube allocation


Hello,

Greetings from Costa Rica.

I'm a really fan of hearing jazz and electronic music too (weird I know)

At this moment, I have a Jolida 502B with Paradigm Monitor 11 v6, Xindaq DAC and CD Player.

I'm trying to upgrade the Electro Harmonix original tubes and looking for this I asked at tubestore and they answered me:

"You require one 12AT7 and one 12AX7 per channel." (actually the 502B has a salad of 12AX7 brands)

So, I will need a matched pair of 12AX7 plus another mp of 12AT7, that's clear.

My question is: where is the correct location or side for to the AX7 and the AT7 ?

There are 4 sockets, guess left-right = two for channel, but I don't know where to put the AX and AT, outside or inside of each channel ?? Or there is another distribution possible ?

Thanks for your help.

From the far left. AT7 then AX7 another AX7 and then on the far right side AT7. Two center tubes are AX7's.
Edoll,

I'm not sure what tubes you are refering too? Anyway be careful getting on the NOS tube rolling wagon. Expensive and you may be dissapointed. You may be perfectly happy with some new tubes like JJ or EH and save a lot of money.

You may start a thread and ask for advice on new production tubes. Good luck!
Don't get me wrong. I really like NOS tubes. I have a nice hoard to prove it. But you mentioned that shipping and customs duties where high in your country. It can get very expensive trying NOS. You should have some tube guys around. Don't give up!

I have never tried the Genalex tubes. I have tried the Full Music and Pasvane and like them both. But they are not cheap.
