Hi All. I have a 50 watt Crate VFX 5112 V Series 50 watt amplifier. I got the amp for free a long time ago and its tubes are going. So I'm replacing them. I put on a pair of rubber gloves, made sure I wasn't fiddling with any capacitors, and pulled the old tubes. The following video shows the process (on a similar 30 watt amp) I went through to remove the tubes.

The tubes from my 50 watt amp are different from the ones from the video. I pulled the following tubes from my amp:
2 X Groove Tube GTEL34R (Power tubes)
4 X Groove Tube 12AX7EH (pre-amp tubes)
My question is, can I just order these same tubes, plug them in the empty sockets, and go on my merry way? Or is there any kind of tweaking involved in swapping in new tubes? Also, my old tubes are made in Russia. I'd prefer to boycott Russian products. I'm wondering if there are alternative/possibly better/possibly cheaper tubes I can use as replacements. Any suggestions or tips are appreciated.
