Hi
This looks like a sensible news group! who but sensible people would want to repair and play with Old Knackered Radios ![]() Being a lonely Brit trying to refurbish an old American Radio I'm a bit stuck, I have repaired the old girl and it works very well after sitting in a garage for many years as a home for spiders, But I can't seem to align it correctly in as much as I can't get the osc to track the dial reading and keep it in good spec across the band? also I'm a bit worried about the bandspread dial, it reads 100 with the tuning cap fully in this means as you go up from 0 to 100 you are going down in frequency? is this right? or has someone strung the dial cord incorrectly? do I align it with the bandspead cap fully meshed or not? I could really do with the alignment instructions has anyone got them out there? I've looked for a manual but they either want lots of $ (whatever they are ![]() are available don't have the circuit or alignment details ![]() Also ![]() I'd love to respray it but don't want to lose the original transfers or logo, any help very welcome from Ron G3YUH |

The bandspread cap must be fully open to align the radio. The bandspread dial might read "Set to zero for normal tuning". If so, it should be at zero with the bandspread cap fully opened. Both knobs should close it's respective tuning capacitor (lower frequency) when rotated counterclockwise. I mention that because the dial stringing diagram is incorrect on my service manual. The oscillator frequency is above the signal frequency on bands 1 - 3 and below it on band 4. The BoatAnchor Manual Archive has the service manual online: http://bama.sbc.edu/hallicra.htm So, how hot does that ballast resistor get? Frank Dresser |

![]() Hi Frank thanks for the info, I wish Bama did have the manual but when I download what they say is the manual all I get is a couple of pages on replacing the ballast resister ![]() from Ron....

The S-77 is described as the AC/DC version of the S-40B. The power supplies are the major differences, the alignment instructions should be the same. So, try downloading the S-40B manual, or any of the others from the S-40 series. Frank Dresser |

![]() Also whilst on the subject of refurbing these old beasts are there any new panel transfers available? so I could have the front and cabinet resprayed and re lettered? Like the Halicrafters logo and the red and white lettering I've seen new dials for the R1155 so maybe someone is producing these items? from Ron...

![]() Yep you are right again it was my plug in, it has some sort of bug in as much paging from 1 down it just circles round the first three pages? If I start from the last page up then I see the manual!! weird one. All ok on the old S-77 it is one fine receiver now that its realigned, I'm afraid I gave in and modified it slightly as it kept blowing the mains trip in my house, I've fitted a small mains transformer on the chassis above the smoothing cap and rewired the heaters to parrallel from serial and changed the audio and rect valves to 6.3 and it really is ace! I've left all the original wiring in place, nothing chopped out so it could easily be put back to original, thanks for all the help. from Ron g3yuh.....
