I do spend time checking every one and replacing the ones that are While I do not take time to replace all of them like I should, Found out that many times the 1/2 watt resistors have changed I started playing around with the old Heathkit transceivers a year or I only work on my own equipment now and if I find one bad part and thereĪre several more like it of the same age (on very old equipmentĮspecially) I usually replace them all if not too expensive. Probably ok, but I was not going to chance it failing in a day or month I told him it was costing us a few thousandĭollars for every hour the machine was down and lots of money to get him Motor was 3 phase 480 volts at about 200 or 300 amps. I believe in replacing all the old parts if one has failed if the costĪt work we had a factory man in to repair a motor speed control. > Or, "I saved $0.45 not replacing a part that hasn't failed yet." > "My time is VERY important, I can't be arsed to replace something." > The other reasons are equally fraudulent. > on the bench when the "there was more than one" suddenly fails. > finding "that one part" while risking collateral damage to the thing > Apparently, some people think troubleshooting means wasting time It's not called shotgunning, it's called not wasting my time. Going to waste my time "trouble shooting" things I know are Replace all the paper and electrolytic capacitors. When I get a radio to work on, the very first thing I do is

There are about US$18 worth of critical parts to be replaced in the typical ST-120, and "doing all" vs. So, if part X is bad on channel A, I will do the same part on Channel B as well. To do any level of restoration mostly requires a complete tear-down. I restore a lot of vintage solid-state Dynaco products, mostly for fun as they are so basic. And, if one is 'in there' the cost of a few capacitors now, vs. And in a design as (relatively) bullet-proof and simple as the 1702, that would lead, typically, to age and/or dirt.
But as-reported, the symptoms were indicative of age. Depends on brand, and the heat in the product.Īlways that is possible. > removing when a customer insists on replacing them all are just as good > Just goes to show you, it is not necessary to replace every electrolytic On Friday, Augat 8:32:53 AM UTC-4, Tim Schwartz wrote:
