Amps on top?

*G* Like the man said @rodman99999 .....

"Never waste an erection..."

...or something addressing or undressing that situation...

If concrete floored, lay some b&m; but mine is a leased space.

The landlord has liked us for nearly a decade, but Bob does have his limits... ;)

I push enough envelopes already, and as is said:

"Know what to kiss...and When."

Anyway....to dream, perhaps to sleep, ciao, J

@bdp24 -

" The companies that mount their output tubes on vertically-orientated circuit boards are apparently not concerned with that issue. I am."

                          Agreed, but: there are exceptions

                                                   ie:

       Designed to set up their own airflow, but: look like they could do a good job convection roasting one's Prime Rib, if, "on the bottom".  

Right @rodman99999, but those tubes are not mounted on circuit boards inside an amp enclosure, where the heat would flow past circuit components. The Wavestream V8 is one cool (no pun intended ;-) looking amplifier! So is the Atma-Sphere M60.

1)" The companies that mount their output tubes on vertically-orientated circuit boards..."

 2) "...but those tubes are not mounted on circuit boards inside an amp enclosure, where the heat would flow past circuit components. ""

       1) The boards on which the driver and output tube sockets reside, are vertically oriented, per your objection.

        2) boards: inside    tubes: outside  (the exception)

        Another, "cool looking" V8 amplifier, complete with engine stand:

                                    Four-stroke operation?

                                  GOTTA love the chrome!
