Description

Mosfet Amplifier

Maplin in the UK sold these modules back in the 80's and were a big seller. Maplin's stopped selling these years ago before they shut down all stores. SO... i have decided to update and release a newer version. I had lots of issues sourcing some of the components and have had to get alternatives. I have included 2 formats for the mosfets as the originals are now obsolete but some are still out there. the new mosfets are available from profusion in the uk https://gb.profusion.uk/uk/audio/transist/lateral-mosfets the best ones i found are the ECX10P20-W6 and ECX10N20-W6 .

I have decided to update the design a bit to include another preset pot for DC offset. i have done this due to the varying hfe between TR1 & TR2. I will update this soon.

If you want any more info please leave a comment
