The beginning...
These two Quad II's will
feature regularly in Quad World as
we track their repair and reconditioning.
Structurally, the Quads were fairly sound
- one can be seen here still fitted to its rack mounting
tray, but this is very easily removed, and the metal-work of both
Quads was fine. They will be re-sprayed,
so damage to the external finish is not a
problem.
|
| The mains, signal,
and speaker connections will also all be replaced
with newer, better quality
and more universally acceptable ones. The
connecting block seen here on the left-hand
side of the Quad II is a bit of user
modification. On opening up the Quads,
these blocks were found to connect
through to the main output transformer,
and seem to have been used to remotely change the speaker
output impedance... |
 |
 |
The extent of the rust,
grime and transformer
tar accumulated on the exterior of the Quads
can clearly be seen here. Unfortunately, the valves
had been removed, so the valve
sockets had also filled with this gunge.
The body of the Quads
need to be spotless for the new finish to
fix properly, so a great deal of cleaning
will be required... |
| These amps were built by
Quad (or more accurately, The
Acoustical Manufacturing Company) for Rediffusion's
TV/radio installations and therefore have different ID
plates from the usual Quad ones... |
 |
 |
They also have an additional fuse
to the standard Quad II design - a 500
mA on the 330v high tension supply
line, which I guess was an added precaution
that Rediffusion asked Quad
to include... |
| Besides the extra fuse,
the different ID plates, and the easily reversible
speaker impedance modifications, these Quads
are entirely standard, and should perform as such when the repair
and reconditioning is complete. (Ummm
- how wrong could I be?! See later sections...)
see work continuing?...april
