The AT93 has a lot of discrete parts, not sure though.
I have somewhere a test of this tuner, in magazine Audio & Techniek (in dutch!)

Thanks for the tip jean-paul. The case is warmer than I'd like and was thinking about modding it just for that reason.

The buildup of heat was the reason these tuners were dumped here in the Netherlands. First factory mod was a 3 or 4 mm alumunium sheet under the transformer to cool it

I made a new power supply pcb with larger heatsinks and separate 15 V regs for each section that had the same outline and mounting holes as the original pcb. I modded 4 AT93 tuners with them that still work today.

Unfortunately AKAI was in the stubborn opinion that decoupling caps were not that necessary. So the tuner can use some extra caps at the rails. Certainly the display supply can use some decoupling as it sometimes flickers.

I've just these on ebay, can't complain about the price.


Will all/most of the At-93 circuits run on 12v 0,5A?

Think I'll get 5 and see if they're OK.

FM Tuners don't get much more vintage than this Pilot model:

IMHO Leak throughline, early mono one with good quality stereo decoder (not the leak internal stereo decoder though).

I also rate the Rogers T75 which is a nice item and can be picked up cheap (the Rogers T100 is very good but extremely rare).

A later tuner maybe try the sony 3ES tuner (I know cheap and sony but very very good but not quite that vintage sound)....

The early sensui tuners look good and sound very good.

Don't rate revox ones at all but it's all personal opinion.

Very splendid. However, it's not a proper radio unless it claims to be able to pick up "Hilversum".

One of these days I will get around to designing a decoder for my Troughline...

Hi newbie123

I use a Leak Troughline 11 tube tuner, sometimes rated 'the world's best tuner'! Hey, hey, I'didn't say it, I read it somewhere and only wrote it! Seriously, after this potential rat's nest statement, I like it for it's sound (I left it mono) and its gold and brown oldtimer styling, the flywheel effect tuning knob and it's 'magic eye'.

And I'm lucky enough to drive it with a Leak Stereo 20 tube amp.

Good weekend to ye all!

If you can find one, the monitoring receivers made by Decca Special Products for the BBC and other broadcasters are very good indeed. Relatively modern (drift-free) tuner design, and a pretty good stereo amp (some with an excellent phono stage and/or balanced ins and outs) built in.

Hi All,
I can add my bit for the Leak Troughline 2. bought one on EBay in the UK got it sent to a company called One Thing Audio to add a new stereo decoder, a service then sent to me in Australia (ouch, the postage cost) but it is one of my best purchases. And will only grow in value, but mine will stay with me until the grave

Howdy, Here's a nice tuner you can pick up for a song when they show up on ebay. I think I paid 60$ for mine a couple of years ago.
