Quad FM4

Stereo FM Tuner. Late grey version, with gold RCA sockets - Mint & Boxed.

Here is a wonderful example of the classic Quad FM4 tuner. Previously in use with its matching 44 pre-amp, 405-2 power amp, this FM4 is in full working order and excellent physical condition (see close-up pictures). We have just fitted a brand new memory battery, so this will not suffer from the common leakage problems with this particular model.

Picture 5 was taken while just using a short length of speaker wire as an improvised aerial.

Currently operating on 200-240 volts, conversion to 100-127 volts simply requires moving a couple of links on the power supply board (see picture 15).

USA and Canada use a different FM de-emphasis than Europe (50u sec EU / 75u sec USA & Canada). There is a very simple modification to make for USA & Canada. This involves inserting two small capacitors onto the underside of the circuit board and is clearly explained in the user manual.

This is supplied in original Quad carton, with original user manual, original Quad gold RCA cables, mains cable and indoor aerial.
