    You may be able to use the 12AU7 with an adapter but the EL84 is a pentode with a heater current of 750mA and that won't be suitable.

    Go to and look around. If you want warm, try the 6cg7. If that is too warm, try the 6922 or ecc804(they are inexpensive)

    The 12au7 is a twelve volt tube. You would need an adapter and a 12 volt power supply for the heater

    Totally agree with you about ECC804. It's a very good, under-appreciated tube.

    Yeah it's a price for a lot of 3, so considering the fact one EH6922 costs about the same on amazon (plus shipping since I'm not from the states) I thought this might be a good deal. Even if I won't use the other two. I've tried searching on tubedepot. I managed to find the ECC804. However, I got multiple results for the 6922, some of which were rather expensive. Could you link me the exact one I should be looking for?

    Tube Depot has some deals on some interesting tubes.

    Correct me if I'm wrong but won't a Western Electric 417A work with an adapter? I think I read somewhere someone really liked it in the Vali 2

    Save yourself some time and buy a 2C51/5670 adapter and start rolling those tubes. Vali 2 can hold its own with much more expensive amps. Don't underestimate it based on its price.

    Try one of these -

    Brand Spanking New, MINT NOS NIB 1970 Amperex/Philips PCC88 7DJ8 A-Frame Dimple Disc Getter Tubes with Dario Miniwatt Label. Identical DJH 40J2 Heerlen Holland Production Date Codes (first letter 4xxxx, 4=delta or left triangle for Heerlen Plant). Boxes are a bit fragile but the tubes are pristine. Very musical and desirable tube in the PCC88 family.

    I have one and they are awesome. 50 bucks but you won't have to buy an adapter or another tube. I have half a dozen 20 dollar tubes I'll sell for 50 bucks so I can buy another, lol.
