I recently purchased a SW7800 receiver in perfect condition. Works just fine. I am looking for someone who would be willing to "give" me a copy of the manual....

Dear all, my SB-102 is back on air after some repair and alignment! Real fun to work with it. What is not working is the S-Meter. It is by far too less...
Hi, did a similar job when restoring an old Swan 350 and it gave a very nice shine again. WIth my SB-102 restauration I face now the challenge how to clean the...
The SB-102's S meter circuit, like all of the HW-100 and SB-100 series transceiver's, is in the cathode bridge circuit of V3 (6AU6 first IF amplifier)...
What Mike has suggested should cure your problem. He is very thorough. Also, replace R-106, a 22K 1 watt resistor, with a 22K 2 watt wire-wound resistor. Heat...
Last night I noticed that when I turned my SB-200 on, the signal I was listening to took a sudden dip in frequency, then returned to frequency very quickly. ...
Stef I would use a spray electronic contact (tuner) cleaner, but not the type with a lubricate. Also on printed circuit board..... spray flux remover works...
Also, make certain that R-107 is at least 1 watt resistor, not 1/2 watt. The following is from Heathkit service bulletins, also on the Glowbugs website. "...
I have for TRADE only , a SB-200 (I call it a SB-206) Heathkit HF+6m amp. The bands it will operate on are: 6,15,20,40&80m (With tweaking you can coax a little...
The article with the above title, and published in PDF format on the Glowbugs website, in my opinion, contains very valuable advice. I have done most of the...
Hello Kenneth, I agree, your HW-101 more than likely has quite a few resistors that have increased in value. What may "appear" to be working properly may, in...
... True, indeed. We often get so used to the way things are working that they can slowly deteriorate and we will never notice. I probably should have said it...
Dear all, many thanks for all the good hints! Especially Mike spend a lot of effort and now I'm back from trying o couple of things: The previous owner did...
Hello Stef, R106 is V3's screen voltage resistor. My SB-102 schematic shows R106 as 22K. If your schematic shows an increased value for R106 from 22K to 33K,...
... Mike: I don't think Heathkit ever changed that value. At least, I have never seen any mention of such a change in the Heathkit Service Bulletins. It may...
... I find those changes to be rather strange. Might you have any idea why he did those? ... Hmmm....that is interesting. ALL my schematics, in all my original...
The SB-100 series has a sidetone volume control mounted in the rear, on the audio board. Many (all?) HW-101s use the same audio board as the SB rigs. There is...
hi I HAVE A SB-100 HEATHKIT, WHICH HAD A BW CLIPPER (barker & williamson hdp-1220) hard wired in it. it was connected with 3 leads, going into the back of the...
I have seen several models of the Heathkit HV regulated power supply. The model numbers I have seen are: IP-17 IP-2717 IP-2717A SP-2717/2717A IPW-2717/2717A ...
I'm not familiar with the B&W addition to the SB-100. One question I have is; Are the wires connecting the B&W processor to the SB-100 have different colors?...
... I have thee of the HVPSs, an IP-17 (brown, Heathkit),an IP-17A (black, Schlumberger), and an UNASSEMBLED IP-32 (grey, Heathkit, oldstyle like AA-1, HD-1,...
Hi, many thanks for the responses! No, I have no clue, why these mods have been done. Actually I got this rig from an OM who never used it and then he gave it...
I have also never heard of such a thing in this amp. I have the amp myself and if you'd like, I can email a PDF of the schematic to you. It will take a day or...
Hello Stef, Yes, the SB-102 "Operation Section" schematic on your webserver "and" the bama website download schematic and the SB-102gif_V6 manual does show in...
Brian, The original post was about the SB-100 5 band transceiver with a B&W clipper, not the SB-1000 linear amplifier. 73 Mike W5RKL ... schematic to you....
