Can anyone remember back in the late 60's Clive Sinclair bringing out small sized solid state amps (no enclosures)? I bought 2 but had mediocre results--anyone else remember these?

I had completly forgotten that Sinclair once made budget audio amps (some in kit form), I never heard one. The only Sinclair product I bought was a Sinclair Cambridge pocket calculator. I was quite expensive at this time, and didn't last very long...

I certainly remember the amp modules. I seem to recall that the model was called the Z15.

A colleague at work used to use them to build guitar amps, in multiples of 15 watts.

My mistake: it was the optimistically-coined Z30.

Was this from the same man?

I'm afraid it was ...

Some early Sinclair amplifiers used Class D amplification. They were ahead of their time in the sense that the semiconductor technology was not good enough to support the principle. They were cheap and intended for home constructors but were unreliable.

Class D has been making a comeback recently (it runs cooler than A,B.C) but it needs modern semiconductors.

Price:
89/6d what a rip of if only that price was today. peter

Thats about £60 in todays money....over priced!

The quoted wattage is only the same as today's modern Transistor amps,
15 watts RMS = about 30 Watts Peak Music Power.

The AD120 is a case in point 120W is 2 channels 60w Peak each, RMS 30 watts per channel.

Valve amps were always rated in RMS watts.

It's a bit of a con trick to catch the layman out!!
