>I am selling my much coveted and beloved Swan Mk II hf amp. It has some
>mods:
>
>1. Tuned input professionally installed. Gear train is slaved to the main
>bandswitch so you still only turn one switch when changing bands. The tuned
>i/p is located on the underside of the chassis via the gear train. Works
>great. Bands covered by this mod are 80-40-20-15-10 but the amp tunes up
>great with full power on 17 and 12. Sorry but I never got around to adding
>160 to this deck although easy enough to do.
>
>2. Vacuum o/p relay installed. If I remember right it is a Jennings RJ1A
>but it has been a while. The input relay is a generic clanker but the mod
>input/output relay mod was done because the original ceramic relay crapped
>out and these relays were on hand. Works great.
>
>3. PS Electrolytics were replaced a few years ago. The Ep on the "ssb" mode
>is around 3100 and very gently pegs the 3kv meter, the "cw" mode is around
>1800 volts.
>
>4. The previous owner added soft start that only works if the amp is wired
>for 240. The compononents are still there but I bypassed this mod. You will
>have to revert it back to how he did it if you want to use this mod (this
>soft start must be completely bypassed for 120 vac operation). The
>schematic is in the manual.
>
>5. New(er) 3-500Zs. I do not remember if they are both Eimacs or if one of
>them is an Amperex but the deck does full output, or the typical 1300 to
>1500 out depending upon the band. I also have a spare full out (used)
>3-500Z. Again, I do not remember if it is Eimac or Amperex. This comes with
>the amp.
>
>6. Fan speed mod. Potentiometer added to the rear of the power supply to
>control the speed of the ps cooling fan. I always leave it on max.
>
>7. Cooling fans for the deck and ps were overhauled two years ago. Fans
>were taken down to parade rest and the bearings were re-packed. Fans are so
>quiet that you can not even hear them when turned on.
>
>This amp has been working great for the last two years and I hate to sell
>it because it works so good but for personal reasons I must sell it
>
>Price is $700 + UPS ground shipping. Three boxes: rf deck, supply, tubes. I
>have no pictures but the condx of the amp is very good to excellent. If you
>are not happy I will refund your money.
