Have noticed that when you have a dodgy bit of tape that the Hi-Fi track
disappears and you get the horrible muffly, buzzy, hissy linear mono track
for a few seconds.

NICAM doesn't actually have anything to do with the recording or playback,
it is just the high quality audio signal which is digital that comes on the
TV channels, So you receive digital audio but still analogue picture.
This is the case in the UK anyway, don't know if you have some equivalent
where you are or not.

Was the dBX type 2 method the combination of Chrome and Metal tape or
something?

Well believe it or not I have one and just wondered if anybody had heard of
it, it is a 1981 110Watt amplifier with a heat pipe, lots of fins and an
old stlye volume control, might be old but it still sounds good, as long as
your not looking for surround sound or anything fancy.
Talking about surround sound has anyone here heard of the Hafler Surround
method?
Cheers for now, Nick.
