I have just re-capped the power supply capacitors in a DX-40 with 40uf 450 VDC
Aluminum Electrolytics from NTE Electronics in New Jersey.

I have noticeable hum on the carrier. Measuring the ripple voltage with a 10
Megohm ac coupled meter shows 2.3+ volts [average/rms ... non-sinusoidal] on the
600 vdc line and 1.2 volts [average/rms ... non-sinusoidal] on the 300 vdc line.

It appears the RS of the capacitors is way too high.

What manufacturer or brand are others using with success? Does MOUSER carry
suitable replacements? If so, what brand/style?

Other sources?

TIA
