Take a look at the filter circuitry and power transformer. Never assume previous technician's work was correct. Is placement/polarity/value in accordance with schematic?

Is power transformer a replacement?

What are filter cap replacement's values compared to what is called for on schematic?

Was radio totally recapped or just electrolytics in filter circuity?
