EAR 864 V1 V3 Tube Type

Can someone tell me the tube type of V1 and V2 in EAR 864? This is what happened, I removed the stock ECC82 and ECC 83 wanting to replace with NOS tubes. When I want to put in the NOS, I realised that there is no printing of tube type beside the tube socket, just V1 and V2 and I have forgotten V1 is ECC82 or ECC83? :(

Thanks in advance.

In my system, I use a clear-top RCA 12AU7 and a 1950s D getter, ridged black plate Sylvania 12AX7. Other systems could use other combos but the RCA is easy to find and relatively inexpensive. It has great bass and dynamics. I found the Mullard 12AX7 very good but less balanced for my system. Some use GE triple mica lower voltage 5751 tube type which is extremely detailed sounding (I prefer less resolution and smoother/warmer sound). Enjoy.

P.S. I don't like the stock tubes at all. Brittle and bright sounding, yuk.

I forgot to update my info.  I changed from the Sylvania (two went dead one year apart) to a Mullard CV4004.  It is a military tube and has no relation sonically to a typical warm Mullard.  It has an extended frequency response at both ends, super dynamic, clean, clear and neutral but full bodied mids.  I love it!  It is also very expensive as an NOS tube (bought at $125 back in 2010).  However, there is an apparent new version that is cheap from Upscale Audio.  Have not tested that one.
