This bulletin describes a modification to fix a problem of low modulation output when using a noise cancelling mike. It is a very simple mod of just removing R625 and then jumper the pads where you removed R625 from. If you decide to use a different mike with a higher output after the mod has been done, you adjust your mike gain to your preference. The mod worked great but when I turn on the echo switch, I have no modulation output. Turn the echo switch off and my modulation returns. There was no note of this in the service bulletin. I have the newer model with the 2SC2290 finals. I want to keep the mod but also want the echo to work when it is turned on. Any new info or suggestions to cure this? |

are you shure you did not acidently jump near by pads out i did this mod on my 200 and acidently shorted the pin next to the one i was jumping out and had the excact same problem, i went back over my work with a parascope and found a small hair of solder i removed it and all is good now..
p.s. i used a variable resister instead of just a jumper and found even better modulation levels and quality, its adjustsable inbetween both extreams instead of one end or the other..
hope this helps, happy 73's

i do not think that private info such as account numbers, should be asked for nor given.no offense but, no. On the question i had asked- could someone confirm tsb 10051 or post it for all to read. |
