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.

HI
In my TR4-c you hear a noise in the background of AC.
In addition to the power supply capacitors on AC4
Question:
1) What capacitors can create this noise of AC
2) "Ac noise" can be caused by the Multi Capacitor C-145 , what are its
characteristics
I thank all
Frank
