For CW/SSB I liked the Alpha 78. The broadband tuning allows quick
band changes (only have to flip band switch - no tuning otherwise).
But it did get hot running RTTY at full power.
I now use an Alpha 77Dx (one tube) which runs cool on RTTY, but takes
a little longer to change bands with the load and tune controls to
