After-market Solution to replace the D-8 power supply for McIntosh C8?

Is there a solution that offers simple plug-n-play compatibility to power these things up?

I don't intend to learn how to solder electronic components at 74 yo.

While there are some tube preamp power supply products on the market, you still need to make some modifications and solder a plug to connect the power supply to the C8 preamp.

Unless you can find the D8 power supplies from the used market which is plug-n-play, otherwise you'll need to ask someone to custom-built it for you.

Thanks!  I can do basic soldering as my ex-wife did stained glass as a hobby. Do you know exactly what I should buy and where I could get step-by-step instructions to pull this off?

Much appreciated- thanks again.

This vintage McIntosh C8 mono preamp is over 60 years old! Some faulty parts may catch fire or explode when energized. Before you spend money on a power supply, my advice is to send it to a competent technician for inspection to make sure the unit is in working order to avoid any surprises!
