Makes sense really... When it comes to the design, construction, and 
sales...the 6-meter amp has the same expensive components as the HF 
amp.  IOW the PS (transformer), control circuits, metering, and 
protection circuits.

What they don't have is a band switch, or a "tapped" (multi band input 
and output).  Many HF amps don't have a tuned input so there is even 
less difference.

With the really big 6-meter amps that will run the legal limit, digital 
key down, or contesting the difference between HF and 6-meter amps runs 
between $500 and $1000 but we are looking at amps costing in the 
neighborhood of $4,000.  Compare the prices of the manual tune Alpha, or 
Emtron for 6-meters with their HF counterparts.
