Oggetto: Re: [Drakelist] AC Noise Rumor On TR4-c
Frank -
Check with Tom at www.hayseedhamfest.com. He has complete capacitor kits
including the twist-lok
for the TR-4C.
C145 - original
A = 20 uF @ 250 VDC
B = 60 uF @ 250 VDC
C = 10 uF @ 25 VDC
D = 10 uF @ 250 VDC
The 250 VDC sections really should be at least 300 VDC, as typical voltages run
about 260 - 270
VDC. I believe Tom supplies either 300 or 350 VDC caps.
