Subject: [Amps] Interesting new amplifier
<4Z4RB has been selling amplifier boards on eBay for some time, but I
<see he now is selling a complete amp (less power supply) at a pretty
<good price:
http://www.ebay.com/itm/1500w-2-x-LDMOS-LINEAR-POWER-AMPLIFIER-LEGAL-LIMIT-/162503347501?
<Obviously not FCC approved. I suspect he gets around that by claiming,
<in effect, that it is homebrewed. Is that legal?
<I sent him a message asking about duty cycle at full power and if a
<manual can be downloaded. Waiting for reply.
<Does anyone have any experience or comments about the amp or the
<seller?
<73, Bill W6WRT
## Looks like a bargain to me. He also makes a 1 kw amp with a single LDMOS
device.... $1600.00 ( also less power supply).

## The 1.5 kw amp Bill mentioned above is $2400.00 ( less power supply).
Both amps cover 1660-6m...and both contain 7 x LP filters. I dont see 30M
band on either of them though.
## either of them can be driven with just 5 watts. He has a 5 / 50 input on
the back, so a 10 db attenuator can be switched in for your typ 100w xcvr.
## he also offers an optional vac relay. Rated for AM, FM, SSB, CW. No
mention of duty cycle or imd etc.
I nominate Bill to race out and buy one, then evaluate it for the rest of us.
