Quickie Vid Input for CTC 5
Installed this quickie Video input on a CTC-5 with bad tuner
(will also later try official RCA circuit others have posted)
*Lifted cathode & Plate resistors on V7b (Noise Inv half of 1st Video tube)
*Added these parts from this circuit off web under 1st Video Cath Follower tube
*Disconnected Vid Det wire wrap & connected this circuit to grid (may need DC Rest)
*Connected signal from 1st Vid cathode directly to Sync Sep C101 instead of thru Noise Inv (was surprised this worked as Noise Inv had gain?)
*Installed RCA socket in rear chassis existing gap
*Will add another RCA for audio
(all mods reversible & non-destructive)
