Thanks for the info Buddy. Looks like Hayseed Hamfest might have what I need. They have a recap kit for the Knight T-60 that uses 700 volt caps. I'll check with them.

Ham Radio Circuits and Repair / Old Knightkit 50 watt transmitter capacitors
« on: May 08, 2018, 02:28:08 PM »
Hi guys, new to this forum but really enjoy the videos on YouTube. I am restoring an old Knightkit 50 watt transmitter and want to replace the 60 year old electrolytics in the power supply. They are 8 MFD 700 volt caps. I checked the Just Radios site that has been recommended on YT but they only have up to 600 V electrolytics. The manual says the Key Up voltage on the 5U4 Rectifier is 720 volts so I don't want to use use the 600 volt variety. I'd rather not put ones in series to increase the voltage rating say 2 350 V caps to make 700 V unless I have to.
Any suggestions on where I could get suitable replacements  or what I should use instead?

Bill
