newbs about tubes

Hello,

I've finally saved up and set up my entry level analog system. I settled on a jolida 202a for an integrated amp. It came with tubes and sounds great. I just have a couple questions if anyone can help me out:

1. The main tubes are EL34s What are some good tubes for this amp and where can I find them.

2. I need to get better RCA cords, what are some cords (not too crazy priced)

3. I'm going to pick up a voltmeter this weekend to bias the tubes. What is this I keep hearing about "rolling" tubes, is this the same for biasing?

thanks!

rolling tubes just means to swap tubes for another brand to enjoy the different sound they may offer

try DIY cords from VenHaus, I paid about $60 each for mine and realized a huge upgrade

Ruby makes great sounding tubes. I use them in my Cary V12R amp. They can be purchased from Cary Audio, or from ruby tubes.

thanks for the tips. one follow up question. Is it a problem to keep the amp on extended periods of time?
