Most hams who frequent the HF bands eventually yearn for that extra punch an amplifier can add to their signal. We might all thirst for one of those legal-limit "powerhouse" amps but the family budget often demands a more affordable approach. Our new CENTAUR is only $749 and packed with all the essentials for SSB, CW and even digital modes.

Your 100 watt transceiver will drive CENTAUR to 600 watts output. Run full power in a QSO for as long as you like in SSB and even CW mode. It's built to take the abuse! The RF deck and power supply are housed in a single, attractive, desk top enclosure that looks great in any ham shack.

Competition has long offered low priced amps but our goal was to do more. We wanted to offer the best VALUE in the industry. Compare for yourself:

Full Break-in CW Yes No
Hot Switching Protection Yes No
Built-in Wattmeter Yes No
Cooling Fan 100 CFM 25 CFM
Power Transformer 21 Lbs 17 Lbs
Filter Capacitor Rating 2000 volt 1800 volt
Matched Rectifiers Yes No

CENTAUR carries the usual TEN-TEC one year warranty on both parts and labor. And our legendary service is there to back you up if you ever need it. SVETLANA warrants the tubes separately. If a tube fails, replacement is free during first 100 hours of use, cost is pro-rated up to 1000 hours use during the first year.
