CZ5/6A electronic schematic diagram

[ken(toronto)]

Does anyone have a schematic diagram?

The headphone jack on the CZ6a sends out too much volume. Even with the volume control dialled to minimum, all headphones connected to it is too loud, hurts the ears! There must be an internal control that cuts back on the volume.

or go to Modifications Forum.
The quickest fix might be adjustable headphones-turn them down till comfortable.
(If you have super efficient headphones they can be louder too; 4 ohm is twice as loud as 8 ohm; double it again if using 2 ohm.)

Thanks Vlad,

No, Fisher will not sell nor provide any schematic as they are trade secret; they also claim it is an obsolete product and they don't have any schematic for it anyways (which I believe is a lie, as they fixed U2Robert's cz5).

I'm sure he has the info, and can effect the repairs if needed.
(I've known and used him since the early '80's.)
