Russ;
Fortunately, in the case of the Rowe-AMI power amp a 6L6 conversion would probably fit, unlike a tuner-amp there is no cage or lid over the top, and the chassis is fairly large as I can recall, but some measuring might be in order to see if octal sockets might at least fit. Then we might get away with using Russian/Soviet 6P3s or metal 6L6s which are more compact then 6L6Gs/6L6GBs etc.
EL84/6BQ5s are another winner in the hot running and self destructing tube department, (basically a 6V6GT in a small envelope), depending on how hard they are driven. However at least those are 9 pin, and were made, and used, by many manufacturers in many countries, so one has many more options for replacement.

Arran
