Colin,
Guess you hit the nail there! A very good approach and is'nt that what we all
want to do,
build and try more amps as the opposite to just discuss and argue about them.
Compare to sex if you like... ;-)

> In my case, I have about 10 amplifiers. All are bandswitched. I really use

> bands after the amplifier is installed in operation.

> It would have been much simpler to build an amplifier for a single band.
> Output could be a Pi-L, the rf choke would be optimized, rf layout would be
> greatly simplified with a very slight increase in efficiency and I would not
> have to worry about some visitor turning the bandswitch (since I really
> never check the tuning as I never move it).

> It is an excuse to build more amplifiers.

> The downside is that the market value of the amp is almost zero - but since
> I never sell anything I acquire anyway (except old cars), that should not be
> a big deal. Leave instructions on the inside of the cabinet to convert the
> big amp to cb after you go QRT and the significant other can come out ok
