i am thinking rack with glass shelfs but i need lots of separation for the tuner because of hum and noise, should i do separate racks or a simple pedestal or leave lots of room between the two. the tuner is very sensitive to the amps transformer and i have limited space per my girlfriend any suggestions will be very

sounds like there is something wrong with that amplifire …. its first time I have heard
about that isue from a stereo set that is matched when bought…. I presume
you bought a set of the same brand
if you have the antenna in the same room like many have …. theese T-antenna´s
that many just place on the floor behind the shelfunit … then can that be the reason
of many werd wicked noise problems in the amplifird signal

the easyest part of course is to place the two units as long as possiple from each other
but that doesn´t cure the patient :-)

other problem makers can be if you have tooooo long wires curled up in a werd role
behind the units = noisemaker sometimes ….. even the lenght of the amplifire wires can
course problems

sometimes when I have opened a tuner , amplifire , etc. I realy wonder how they can work
without any noise at all
if you have a sinus signal at low freqvens and and shorten the length of the freeqveens to the half
you multiply with 4 the problems you have to take care for

I realy hope you solve your problems …. experiment a little by coiling the too long wires
before shortning them …. often shorter wires can be bought or made local
to your demands .... sometimes a round magnet where the wire is coiled around 7-12 times
solve the problem

good luck

try to connect an antenna ... having an open antenna socket isn´t good
its not the socket it self that course the problem but the lack of a sheild
its the same if you connect two signal wires for lengthen one by twisting the
cobberwires together the lack of sheild can gives alot of interference noise
it maybee sounds werd to you ….. I can´t explain it better since its over
30 years ago I read and learned the stuff :-)

the design isue thats up to you …...... depends on is it a demand (from the boss) to hide
or do you want to expose the hardware

well i first grounded the amp and tuner and hooked up a simple dipole antenna and no more hum, so now i am going to build a cabinet and put the amp on the bottom and tuner on the top.

Just make sure it has enough room to breathe and dissapate all the heat. These guys get hot, and I know that aint good for them.

yes shane the accuphase amp is only 100 watts a channel but it can put out a lot of current and gets hot at high volume thats why i am thinking of an open air rack like some 12/4 mahogany for a post with 3/4 glass shelfs dadoed in to the post but it will take a special glass connection for that to work.
