Maplin did a lateral mosfet amp based on an old Hitachi datasheet.
I took that circuit and improved it with CCS and better CM and front end decoupling.

An externally hosted image should be here but it was not working when we last tested it.
ECX10N20
Hi
I found a model for ECX10N20 on the LTspice Yahoo Group Files, but unfortunately not for the P version.
I suggest you join the group if you are not already a member and ask there if anyone has models for these devices.

Ian Heggluns lateral fet models are excellent. I can't just find the thread/link to them but they were freely available.
Excellent, thanks for this. I think the thread you are referring to may be this one:
Better power MOSFET models in LTSpice

I use a couple of those bridged for a push-push IB sub. "virtually bomb proof" as the construction sheet that came with the kit said 🙂
Thanks. It could well have been in that thread somewhere. Ians models are terrific.
I seem to remember the 'Bomb Proof' blurb from the Maplin catalogues of the day. The Lateral FET's are super though and I've never blown one yet, and that includes the time I accidently shorted an output line to one of the rails (the JLH 90watt lateral FET amp).
Here is the Maplin amp for anyone wanting try adding those models out.
I've 6 pairs of the old Hitachis still going strong, in various topologies, managed to destroy one a while back but was lucky to find one on eBay for £15, sounds a lot but, hey-ho, they are getting scarce. Re, the maplin amp, before I knew any better I was playing around with NFB gave it 100%, no means to measure but nothing happened and it sounded ok!
Thanks Mooly, that's interesting/impressive. Perhaps it remained stable because it's such a simple amp. I liked the sound of it when I did that, very "tight" sounding. I kept it that way for a number of years until I needed more power from it
Of course, I didn't run it at those kind of voltages, direct cd player as source
