Carver M-400 Amplifier Repair Keeps The 1980’s Alive

Carver is a popular identify in audio equipment though they have been recognised to use odd names for factors. For instance, the 1980’s vintage M-400 magnetic subject electric power amplifier that [JohnAudioTech] is restoring (see the two movies below). That seems like a thing off a poor Star Trek remake, but, seemingly, we weren’t alone in wondering that, judging by this 1982 evaluation of the device from a United kingdom journal.

Even now, it is an appealing substantial-electrical power amplifier and we really like observing equipment of this age torn apart. The beast is rated at 201 watts — you have to surprise if the excess watt is yet another advertising ploy.

There ended up really two models and they seemed fairly very good for 4-10 years-aged bins. 1 sounded rather fantastic outside the house of some noticeable buzzing. The other had a thing shorted inside of. If you get pleasure from viewing mend video clips, you are going to take pleasure in this two-parter.

We have to admit — and it could be a own bias — there is something much more pleasing about looking at a PCB populated with a bunch of intriguing-hunting by means of-gap elements. Contemporary boards with a sea of surface mount sections tend to look a tiny bland, aesthetically speaking. Of system, when it will come time to make our individual boards, we are happy to use SMD and forego all that hole drilling!

We like looking at computer mend video clips, in distinct. Or at times, a little something seriously exotic. at?v=oLsYv6tzP1U
