I just picked up a Jolida JD50A "passive preamp with remote control". I installed it last night and discovered that unfortunately it won't cut it. At max output it's barely loud enough for my requirements. It's fine for tv, but for serious listening I need just a touch of gain to make things happen. I previously used a 12SN7 SRPP preamp that sounds good and has lots of gain to spare.
The nice thing is that now I have a huge, nearly empty, chassis. Why let that go to waste? I immediately thought of converting it to a *simple* tube preamp so I could still use the remote but get a little gain.
Here's what I have in my inventory:
The chassis is 2" high. My PT will fit no problem. The tubes can be mounted horizontially or I could punch holes through the top cover.
My thoughts were a 12B4, 2C51, or 6922 circuit. I prefer to keep it simple and use a CRC filter. Either Tube or SS rect would be fine with me.
Thanks for your comments.

Here's what I have in my inventory:
- One huge Jolida JD50A chassis with all gold RCA's, etc. (already has vents so tubes shouldn't over heat)
toroidal PT- 500VCT/100mA - 6.3VCT/6A - 14VCT/1A
Lots of PS caps, Solens, Auricaps, tube sockets.
