Welcome to the MagneQuest DIY space for home grown amps of particular
merit, using excellent circuits that put music before HI-FI; the
one thing these amps have in common? They all use MagneQuest iron
to get the best out of the design.
Look forward to more schematics and builder comments. See this
as a forum to submit your own gear and/or design using our iron!

SETH 2A3 S-240 Monoblock
by Step Instructions
by Dr. Jean-François
Jean-Francois is back again, this time with a full step-by-step
"how to" with something a little different. Yeah, everyone
is doing SET - Well, why not a stellar 2A3 Push-pull Monoblock?
How about the legendary MQ/Peerless S-240-A for output iron?
Still not enough? Put the MQ EXO-173 in for phase splitting
duties. These Triodes with an Attitude are dropped in a custom
ZEBRA WOOD chassis with copper top plate. Ok, so Jean-Francios has
changed the circuit more than his loafers... Hover your mouse over
the amps for SETH, the latest layout. He finally has arrived
with what he believes is "IT". And we are going to picture
these beasts to death and get others wanting to try SETH, a push-pull,
all triode, liquid gold amp with MUSIC as goal #1. Good-bye Status

Horus 2A3 Silver
[click on pic to see article]
Someone had to be first, but how lucky can you get when the first
is this good! Quebec's Jean-François Lessard is the first
home builder to respond with a full blown article, part list,
review, and schematic for his Horus 2A3 Silver Parafeed
Monoblocks featuring the amazing EXO-35 with a solid
silver wound secondary. Lessard also employs a MagneQuest
EXO-03 Plate Choke and BCP-16Ni Grid Choke, not to mention
the MQ 5500 power transformer. Jean-François
claims this SET is one of the best he has heard, exhibiting the
inherent SET beauty in the midrange while plumbing the extremes
with a solidity and extension often claimed to be missing in many
SET designs. Please click on the Horus
2A3 Silver graphic above!
Parafeed Dual-Mono Amplifier
By Kurt Strain
couldn't have a better choice for the second installment of DIY!
Kurt Strain's single-ended 45 home brew takes no prisoners; Kurt
claims it is the best amp he has ever heard powering the Avantgarde
amp uses a 6H30pi driver with active constant current source (bipolar
CCS) direct coupled to a 45 in parallel feed configuration. He employs
the amazing MQ Cobalt Parafeed EX0-45 to spectacular ends. This
article includes internal wiring shots, the schematic with parts
specified, and comments from builder Kurt Strain. See what Kurt
had to say about his amp soon after break-in:
is the finest output transformer and the finest amplifier I
have ever heard... This 45 amp with this output transformer
has it all.... It is true to the timbre, the pace is lightning
quick without etch or edginess, the bass is awesomely defined,
the mids transparent as can be, the highs superbly detailed
and airy, the depth and delineation of imaging incredible. It's
pure music; there is no amp I have heard that beats it.
