Another RCA CT-100 discovery B8001599

Thanks. Sweep alignment looks pretty straightforward. I inherited from an old TV station its extensive inventory of NOS carbon composition resistors and shall use them to match the original construction. The only improvement I shall include is replacing the capacitors with newer metal film units.

Some of the corrosion was pretty bad and I plan to clean the affected area fully. Sadly, as was the habit of many repair folk, the bottom panel was not refitted allowing the mice to easily crawl into the chassis corner. I was surprised the degree of corrosion the trickle down of the mice urine caused to the speaker below. Fortunately all is fixable: it just requires time and patience.
