How much gain does a LTP have?

President Quayle How much gain does a LTP have?
Can anybody give me an idea of how much voltage gain I can expect from a standard Long Tail Pair Inverter? Is its gain range similar to that of a preamp stage that uses a 100K plate resistor and a 1.5K cathode resistor?

Using a 12AX7 you should expect a gain of about 25 or so without NFB, which is roughly half that of the gain stage you mentioned.  
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.
