Used Heathkit SB-201 Amplifier is just what you need to be heard through those pile-ups. The first 500watts is the most important ... that's why these Heathkit Amps are so popular even today. This one was well cared for and still does a nice job. The modern radios require a little interface box to protect the internal switching ICs from too much current in the switching relay but those can be had for about $25 to $50 bucks depending on where you get them.
I have no manual for this amp but they are often available on .
The 572B tubes look new and the DC voltage on the HV meter position reads about 2400 volts which is normal for these amps.
This amp will be well packed for survival and shipped to your QTH. UPS Shipping is FREE in CONUS. Other methods at your expense.
This Amp covers 80 40 20 and 15 meters.
Thanks for looking.

I put the SB-201 on the bench this morning and checked its performance... this is what I measured thru my watt-meter into a Dummy Load:
80 meter band ...3.840 Mhz with 70 watts in ... key down ... 500 Watts out measuring with my MFJ-986 tuner's built in watt-meter. (not a lab instrument)
40 meter band ...7.172 Mhz with 70 watts in ... key down ... 500 Watts out " " " " " " " " "
20 meter band .14.226 Mhz with 70 watts in ... key down ... 420 Watts out " " " " " " " " "
15 meter band .21.310 Mhz with 70 watts in ... key down ... 300.Watts out " " " " " " " " "
On 40 Meters ... I talked to a couple of stations on LSB and got reports of 5 9 with good quality audio from both when I requested a critical report as I was testing a Amp.

Remember... that under CW key down conditions the power supply DC output voltage drops quite a lot... when using SSB voice peaks of current do not pull the voltage down near so much so the power input and power output peaks will be quite a bit more... usually you can figure 150 to 200 watts more on SSB peaks than you will get with key down... confusing enough for most... ha ha... so my guess is that this amp may put out about 600 to 650 on peaks in SSB mode with most voice types on 80 and 40 meters and maybe 450 peak on the higher bands... thats my guess..
Thanks for your interest.

Oct 25, 2011 ... Last night I checked into a 40 meter net with this amp in-line instead of my usual amp which is a SB-221 Heathkit. I made several contacts and the reports and comments were all good and about the same as if I was using my SB-221. Probably because I run about the same power even when I could be running more. Everything worked smooth and as it should. A great little amp. Good luck in the offers.
