** The reccomendations I made in "The Nearly Perfect Amplifier" [Jan 
1994, QST] amplifier would add c. 10% to the price of an amplifier.  What 
percentage of the Ham community wouldn't like to have an amplifier that 
includes:

*Adjustable filament/heater voltage and a simple voltmeter using the 
multimeter. [$10 to $20] 
*       Step-start relay circuit for the entire amplifier. [$7] 
*       Adjustable transceiver-controlled electronic bias switch. [$2] 
*       High speed RF relays. [$120?] 
*       Low VHF-Q parasitic suppressors. [$1.50] 
*       Separate HV and filament transformers - preferably potted [$60] 
*       Compatible with 100W of drive.
*       Glitch protection diodes for the meter circuits and the negative HV 
circuit. [$0.30] 
*       Glitch resistor in series with the positive lead of the HV power 
supply. [$1.10] 
*       Completely adjustable tuned inputs with a Q of 2 - 3. [$6] 

If I were younger, and I wanted to mfg amplifiers, needless to say, I 
would include all of the above features and say so in my advertisements.  
For those who would like to save c. 10%, buy another mfg's amplifier and, 
as an additional bonus, gain knowledge about amplifier repairs and 
amplifier circuit improvements.   However, for those who take this path, 
a caveat --  Never, Ever write an article for a Ham magazine that 
advertises amplifiers which omit the listed items above.
