i like that mate,what is the covering?
Cheers Jamie, The covering is a mid century modern print on pure cotton fabric. It is acoustically invisible. The filling is multi layered wadding which works great. The best part is you can add or subtract layers depending on the final product you want and potentially which frequencies you want to attenuate.Quote:

If you go too far with the acoustic panels the acoustics will become quite dead and flat, like someone has sucked all the energy out of the music you are listening too.Quote:

JUST before I tore it apart I though I would make sure it was not another issue so I disconnected everything and re routed wiring and changed power cables etc. Now the Pioneer only creates mischief when using the phono stage. No problems with the line stages or indeed when using the receiver. But as soon as I switched to the phono stage I was getting humming and buzzing. A thought struck me it may be an earthing issue or ground issue relating to either the power cable (unlikely) or the captive phono lead which I had soldered into the GL75.
I think my hunch was correct as I have "messed" with this cable and made sure earth leads attached and viola hum has gone. Maybe the tiniest buzz when turning up full volume but nothing like before. So hopefully I have cured the problem and prevented myself going to a whole heap of trouble and spending hours on the mouser website!

Playing very sweet this afternoon with my fully reconditioned GL75. They got some thing very right back then.

Lovely receiver James. Yes I do believe they got a lot right in those days :)
They sound great and the phono stage is very good indeed. Back in the 1970s there was way more competition so stuff had to sound good. They had very useful tone controls back then too which I really like. You can EQ your system in your room with them and saves a whole bunch of box swapping or room acoustic treatment.Quote:

The Marantz amp I have here has tone controls. Never had a play with them (yet) :)
That Loki stuff looks interesting, but (and forgive my ignorance) where would it sit in a simple set up with 2 sources (vinyl and CD) into an integrated amp?Quote:
