Well actually it's at a friends place and the left channel isn't working. But am using the RCA. I know Albert Porter has experimented with more and he told me the tube he ended up with but the model/brand escapes me.
Brought it to one shop and they replaced the gain pots but the unit has the same problem. I'm getting a little frustrated and will need to send it to this other guy David recommended in PA; I think it's the selector switch that is broken since the phono stage gradually loses the left channel and if one switches between inputs, it comes back again. But need to get a box for the unit to ship and don't have the original box. David wants $400 for a new box.
And actually had both versions eg the adjustable RIAA and the simpler model in house. I ended up with the latter.
So it's not my go to phono section any more as we've discussed
