Heathkit SB-240 PROTOTYPE !!!
Hello,
I have a Heathkit SB-240 linear amplifier. This is a prototype!!! It matches the SB-104 line in design. I got this one from my friend Mike Elliot (the man behind SB-104 and Drake TR7). He is now silent key. The SB-240 has two 3-500Z tubes, and built in power supply. I have full documentation for it. I have it stored in USA at the moment. I'm considering selling it for a serious price. That's why I have not got it shipped over to Norway yet, where I live. I don't think there are any more SB-240 out there. I've never heard of any. If you have any more info about the SB-240, please drop me an e-mail. You may take a look at it he http://home.online.no/~sindtorp/sb240front.JPG http://home.online.no/~sindtorp/sb240rear.JPG Regards, Sindre Torp, LA6OP http://home.online.no/~sindtorp |

Heathkit SB-240 PROTOTYPE !!!
Sort of looks like a front-panel re-do of the SB-220? I'll bet the
schematics are identical, except for the metering circuits. |

Heathkit SB-240 PROTOTYPE !!!
Google search seems to indicate that the SB-240 final was/is an 8873 not two 3-500s.

Heathkit SB-240 PROTOTYPE !!!
Hi,
Well, the SB-240 has two 3-500Z tubes. And so says the original manual I have for it. All the paperwork is original and with some comments etc. written by Mike Elliott by hand. Mike told me that he was the man behind it. I'm by the way also the happy owner of the very first Drake TR7 prototype, serial no "XXX1". I got this one too from Mike. I have several other Drake prototypes as well, the TR8 to mention one. Sindre, LA6OP "Dave" skrev i melding . .. Google search seems to indicate that the SB-240 final was/is an 8873 not two 3-500s.

Torp,
Looks like a redo of the SB-220/HL2200. Probably if working you might get $1K USD. Does have clean looks! Dave K4JRB |
