Hi there,
Does anybody know where I can download the Aleph30
service manual? All the references I've found pointed
to the Volksamp site, which is no longer operational.
I also couldn't find it on the passlabs.com.
Many thanks,
Dennis
P.S. I'm a newbie who's lurked around for a little
while and have been amazed at the amount of information
available here. Hope to build an Aleph 3/30 in the future. |

Mr. Harrington will move it over to the www.passlabs.com
site in the next couple of days for you. |

I've looked at the schematics of the Aleph 60 and it's quite similar to the Aleph 2. I am planning to build the Aleph 60 as the 60W is quite sufficient for me with lower heat dissipation. I would be grateful if someone could help me with the following:-
a) I noticed there are two resistors R1 and R8 in the A60 which
is not in the Aleph 2 and the values of these were not given.
Are they necessary?
b) The output of the mosfets are connected to the speakers thru
6 pcs of paralleled 3 watts 1R resistors giving a final
resistance of about 0.17R. Could I just use a non-inductive
resistor of say 0.15R in a 20W TO220 package by Vishay,
meggit, Mills etc?
c) For C17 in the balanced input, could I use a film and foil cap of
say 20uf to 40uf instead of an E cap of 220uf? Would this
affect the bass response?

a) R1 and R8 are trim resistor to get the last bit of
DC offset and PSRR. There is a thread elsewhere on
this site that you can search for.
b) Yes
c) Yes and Yes. |
