eds reply...i asked if he was old phaser and was he sure the 4700 would work....he ignored the old phaser part...ebay reports his location...

Any cap above 3000 mfd 80volt min that you can fit will work. I stock 4700mfd For some old Dynaco amps and have sold about 4 or 5 pair for use in the PL200 over the years. I am and ex Dynaco and Hafler engineer and know the amps produced in the 70s and 80s. I did converse with engineers from Phase and others at the audio shows and conventions in that Era . The only people in those days who offered high power amps wereDynaco, Phase, and Crown. Those were the days. Ed

Easy fix listed on E-bay But you also need a ac wall mount transformer to power it up. https://www.ebay.com/itm/274805430683?epid=24042496083&hash=item3ffbae199b:g:XDsAAOSw~Xxgp524
Did "Ed" give his last name? Harry Klaus was the last Dynaco engineer I know of. He did the Dynaco 400. Attached is the 200 manual. Read the service bulletin about the 200II driver board. The 200 has an output relay that is far better than the one on that EBAY board. Those contacts will weld. The existing relay will likely weld to if the amp fails in it's usual dramatic fashion. It just stands a better chance of survival.
I don't get Ed's comment about the transformer. Some receivers have a fuse wound in the transformer. No power amp that I've seen has one. The inrush current is only significant for the first few cycles. Attached is a screen shot of a 700 inrush. Yellow is the current, Blue is the secondary (output) voltage. The transformer actually limits the current. You couldn't cycle the amp off and on fast enough to hurt the transformer.

i have used this amp for the last few years...
kinda inherited it...from a friend...initially the relay hummed...until i cleaned ir and added a drop or two of 3 in 1 oil...its not really a thump as in the 400...non issue for me...the sx makes a similar noise when its relay clicks on...and thank you!!

On the storage caps. Note the capacity and voltage, then measure length and diameter, and note the connector. Write all this down.
Next, go to Mouser Electronics, and Digikey Electronics, and learn how to use their search tools to find a replacement cap. Pull up the data sheet, and learn how to read it and what it all means.
This is something you need to learn how to do. Any questions please ask. Lots of guys here have mastered this and can guide you.
