"2. Are RCA 807 a safe bet? Did RCA rebranded other manufacturer's 807 as their own? I want to avoid getting 2 tubes with different internal construction but the same brand. :)"

There are a MILLION variations on internal construction of 807s. There was a lot of rebranding and a lot of running changes, so the result is that getting two tubes with identical internal guts is not so easy.

As has been mentioned, the 1625 is an 807 with a 12 volt heater.

The 807 is a 25 watt rated disipation tube according to our friends at RCA, so keep that in mind.

Also FYI, the Russian 807s are a pretty darn good tube!

807 is exactly 6L6 electrically, only with higher ratings. nt - sser2 13:05:00 06/19/07 (0)

Another 807 variant to consider is the loktal 5B/255M. - thermionic addictions 11:23:05 06/19/07 (0)

how about 1625? direct/close equivalent to 807/6L6 but different heater (and possibly pinout)? thanks again (nt) - jarthel 04:52:57 06/19/07 (3)
