Hello Brian
I think you would be wise to steer clear of both the ALS1300 and the
Heatherlite.
>From the reviews on eHam, the protection of the MOSFETs in the ALS1300 seems
poor - this is a crucial failing which also seems to plague 'Expert'
amplifiers. Any protection circuitry in a solid-state amp has to be
super-fast, or intelligent enough to back things off long before the devices
are damaged. Tokyo Hi-Power amps are very well designed in this respect.
All Heatherlite amps are/were poor - a hotch potch of R.S. Components -
badly designed and badly constructed.
In your situation I would try getting hold of a valve amplifier - something
like an Alpha 91B will last a long time. There is quite a wide choice in
this type of amp.
