Hello,
I would really like to build a 100+ watt Exicon ECX10N20 & ECX10P20 or Exicon ECW20N20 & ECW20P20 Lateral Mosfet based amplifier.
Existing examples that I can find,
->From the Build Audio Amps web site, Project #5,
Project #5 100W MOSFET Audio Power Amplifier
But is uses Hitachi 2SA872, 2SB647 and 2SD667 transistors that are no longer available
->Pee Cee Bee's V4 lateral mosfet amplifier,
PeeCeeBee V4 Rev2
But it only uses one pair of output transistors for 50 watts.
->SusyJ has her 50 and 100 watt version of the AEM6000 lateral mosfet amplifier,
Susy J 50/100 watt version of AEM6000 amplifier
But is uses the SST404 which I cannot find anymore. I would also prefer through hole to all SMD.
->Apex FX-12 lateral mosfet amplifier,
Apex FX-12 gerbers by Prasi
Only one pair for 50 watts.
(BTW, has anyone done a BOM for dummies for the APEX FX-12)
-> Elliott Sound Products Project 101
ESP Project 101
This one actually has most of what I am looking for, except Rod is half way around the world and having purchased from him in the past, post from Australia is ssllooww.... I would prefer to be able to have double sided boards made without jumper wires.
Is there a published two(+) pair lateral mosfet amplifier with an easily source-able parts list?
Don't necessarily need gerbers, a PDF of the circuit board would be fine.
Plan B will be ordering ESP Project 101 boards...
Thank you,
David.

take a look at Mooly's Lateral Mosfet amplifier. comes in single and dual pair designs and he offered the gerbers to get boards yourself.

Davefred,
This is Shaan’s higher power PeeCeeBee V4H. It fits your criteria well. I use this amp almost on a daily basis, definitely a keeper!

I think the slewmaster builds include some with latfets.

There is also the TubSuMo hybrid with two pairs of j162 k1058.

Bob Cordell’s DH-220C design could likely use the TO3P Hitachi or TO247/TO264 Exicon devices in place of the TO3s.

I have the TubSuMo and DH-220C amplifiers and like them VERY much.
Lots of good options in this thread!

Jfet input. Dual die exicon ecw. High bias class ab Is the way to go.
Fssa. By fab.
Another if very concerned with watts. Goldmund telos clones {same as jobs 225}. Jim's audio.
Tried plenty of lat mosfet. 50 to 70w high bias is best of both musicality. Drive and transparency . No issues driving Dyn. Nht. Atc. Harbeth. In big room to loud loud thundering volume and bass.

Hello!
Of all the examples, only the APEX option deserves attention.
you just need to re-correct it, and you can safely connect 2 pairs of laterals to the output without equalizing source resistors.
@Sensation45 Which board is this?
Did you finish it?
Thoughts about it?
What transistors did you use?
Thank you,
David.

I thought answer or subject was in title.
Always fun to just see new versions of original Hitachi circuit with 2x output devices.
Seems easy go to classic, just need added constant current source and use modern devices.
