Chris and Grant are right about the sense point. Step 1 50Kc: V3 is removed. The injection point is Pin 1 of T2 not L6. There is no voltage on that pin of T2. The sense point is AVC because you are aligning the .5Kc bandwidth position to anchor the 50Kc I.F. system. The injection is un-modulated because it is the .5Kc position. Step 2 1650Kc: Askes you to use a modulated injection signal. Read through it a few times after you get the 50Kc right. It is essentially written to center the 5Kc wide 50Kc signal in the center of the wider 1650Kc pass band. The radio is set to band 1 and a modulated 1650Kc signal is injected into the grid of V2 the first mixer simulating a signal from the antenna. This step senses at the speaker leads because it is modulated and 5Kc wide. There are no paper capacitors under the sub-chassis. I would not remove it unless you measure a defective component. You can measure all components from tube pins and under chassis connections. Thoughts?

Not quite sure I understand what I see! The S76 schematic uses two .05uf caps --- C21 and C23 in the sub chassis --- the only large value caps under the chassis. The photo you sent points to C27 and C29 --- different numbers??? I had several of the prototype sub chassis and they had ceramic caps??? Apparently they were for the SX96. Have to call the troops back and re-group. I'll copy the reflector with your findings. Charlie is correct in taking the time to pull the sub chassis. As Chris points out the caps are probably paper.

Chris and Grant are right about the sense point. Step 1 50Kc: V3 is removed. The injection point is Pin 1 of T2 not L6. There is no voltage on that pin of T2. The sense point is AVC because you are aligning the .5Kc bandwidth position to anchor the 50Kc I.F. system. The injection is un-modulated because it is the .5Kc position. Step 2 1650Kc: Askes you to use a modulated injection signal. Read through it a few times after you get the 50Kc right. It is essentially written to center the 5Kc wide 50Kc signal in the center of the wider 1650Kc pass band. The radio is set to band 1 and a modulated 1650Kc signal is injected into the grid of V2 the first mixer simulating a signal from the antenna. This step senses at the speaker leads because it is modulated and 5Kc wide. There are no paper capacitors under the sub-chassis. I would not remove it unless you measure a defective component.

Its possible for the new parts to be bad or wired wrong or an inadvertent short from solder or a wire whisker. If there is not even hiss from the audio you might have two problems.

Since the AVC line is being used a very high impedance VTVM is desirable. The generator injection point is the grid of the first 50khz IF. No DC there so decoupling the generator is not necessary. Presumably the amplifier isolates the first 50Khz filter from being loaded by the generator. This should work. I think there is a Sams folder on BAMA along with the Hallicrafters book but I believe it has the same procedure in it.

Turn L6 back and forth. If that oscillator is not very close to 1650Kc, you will measure nothing. If you have a another radio put the antenna near the under chassis and tune to 1650Kc to see if the oscillator is running and at what frequency.

I am using a .01 cap to isolate pin 1 of the 50hz if can (L6 on the Hallicrafters schematic), and cannot seem to get an unmodulated signal through. There is about 270vdc on that pin, so I have to couple to it through some method. Any advice is appreciated. >>> Ken >>> Ft Smith AR. >>> >>> >>> ______________________________________________________________ >>> Hallicrafters mailing list >>> Home: http://mailman.qth.net/mailman/listinfo/hallicrafters >>> Help: http://mailman.qth.net/mmfaq.htm >>> Post: mailto:Hallicrafters at mailman.qth.net >>> >>> List Administrator: Duane Fischer, W8DBF >>> ** For Assistance: dfischer at usol.com ** >>> >>> >>> This list hosted by: http://www.qsl.net >>> Please help support this email list: http://www.qsl.net/donate.html >>> ______________________________________________________________ >>> Hallicrafters mailing list >>> Home: http://mailman.qth.net/mailman/listinfo/hallicrafters >>> Help: http://mailman.qth.net/mmfaq.htm >>> Post: mailto:Hallicrafters at mailman.qth.net >>> >>> List Administrator: Duane Fischer, W8DBF >>> ** For Assistance: dfischer at usol.com ** >>> >>> >>> This list hosted by: http://www.qsl.net >>> Please help support this email list: http://www.qsl.net/donate.html >> ______________________________________________________________ >> Hallicrafters mailing list >> Home: http://mailman.qth.net/mailman/listinfo/hallicrafters >> Help: http://mailman.qth.net/mmfaq.htm >> Post: mailto:Hallicrafters at mailman.qth.net >> >> List Administrator: Duane Fischer, W8DBF >> ** For Assistance: dfischer at usol.com ** >> >> >> This list hosted by: http://www.qsl.net >> Please help support this email list: http://www.qsl.net/donate.html > > -- > Richard Knoppow > 1oldlens1 at ix.netcom.com > WB6KBL > > ______________________________________________________________ > Hallicrafters mailing list > Home: http://mailman.qth.net/mailman/listinfo/hallicrafters > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Hallicrafters at mailman.qth.net > > List Administrator: Duane Fischer, W8DBF > ** For Assistance: dfischer at usol.com ** > > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html From hallicrafters at mailman.qth.net Thu Aug 13 00:40:21 2015 From: hallicrafters at mailman.qth.net (Ken And Susan Hittson via Hallicrafters) Date: Wed, 12 Aug 2015 23:40:21 -0500 Subject: [Hallicrafters] Aligning a S-76 In-Reply-To: <825E980BE9B74BAE900B8A8AE220A9DF@LILESJLAPTOP> References: <69174949-7FB7-47A2-8943-AD4F7C2E2576@yahoo.com> <55CA3A46.8010607@ix.netcom.com> <825E980BE9B74BAE900B8A8AE220A9DF@LILESJLAPTOP> Message-ID: <2DBC954A-2AF0-4856-9689-1C8EC9E2811A@yahoo.com> Thanks Jim I can try listening at the 1650kc freq, and I also can try using a small (goIt) frequency counter, that has a whip antenna to measure the frequency of the 2nd mixer. One thing I found, is that if I dangle a test lead off of T1 term 1, the radio plays thru the speaker (normally) like it is cross-talking between the stages. If I move the dangling test lead loop toward V8 the radio plays very clearly. Removing the test lead results in a quiet radio.

Checking back in: I validated that L6 is at 1650kc by using my signal tracer on term1 of T1. I get a perfect signal there listening to the tracer output. If I tune L6 I quickly loose the signal. I went ahead and removed the 2nd mixer box, and replaced the wires, which had become frayed, and to again check the work I did in there replacing c21 and c23, and r20 and r22. I pigtail wired the Assy up and checked tube voltages, they are as follows: Plate 262.8 (should be 265) G2 141V (should be 80V) Grid -2.1 K-G5 126V (should be 1.5V) Heater 6.27 VAC I only hear a strong signal at the grid, using my signal tracer. The coax output has 265V on it, but only the tiniest signal. Comparing the wiring in my mixer to the schematic it looks to be correct. The K-G5 is fed from the v10 power tube, per the schematic, and hence it shows 126v, not sure why the pin voltage shows to be 80v being fed from V10... Any advice is appreciated.

I am moving to FL and downsizing everything. So, I have decided to part with my excellent SX-115 and HT32B. Beautiful condition, working, and no mods I know of. I have recapped the HT32B. I am asking $1200 for the SX-115 as it is so nice...and $400 for the HT32B as it is also rare condition. Pick up/meet somewhere is OK. Shipping only if you arrange packing/shipping somewhere professional as I don't have a way to do that. Also, I will have SR-150, 2 PS150 PS, SR-400 Cyclone II (include PS) R-47 spk listed soon. (all of these can be shipped) Thanks, 73, Lee, KC9CDT Columbia City, IN (Near Ft. Wayne)
