I am using the M7 PCB which you sold to me half year ago. The dimension of the PCB is 17.5 X 21cm. It is quite large so that I need to use the bigger case which must be 43cm wide one. Do you have that size spare case in your stock? Thank you
Another question:
Is Aluminium case good for connect the ground wire?[/quote]
Dear icefireman,
You can try searching in 麥X in 女人街鴻光商場,I noticed there are some tube amp cases available.
[quote:91840b1c75="icefireman"]Thank you all the brothers' info. About the case, I have ordered an Aluminum case in China. It was R$520 (I tried to show the case later).
About the switch, I have to thank Alcat and Accphoto. Both gave me alot of info. Finally, I decided to add a 0.1uf cap between the switch (L). And I would pick the simple action was turning on pre-amp and then turn on power amp 20s later.
One more question is about the fuse. I should hook up L -> fuse -> switch -> transformer or N -> fuse -> transformer?[/quote]
Dear icefireman,
Always connect in this way: L -> fuse -> switch -> transformer
A better way is to use a 2-pole switch like this:
L -> fuse -> switch -> transformer L
N ----------> switch -> transformer N
and you need two capacitors if you use 2-pole switch.
