"Interesting" DAC90 project
I just bought a DAC90 which didn't cost a fortune. The description was honest enough, "good case and knobs, but some valves missing and insides have been messed with". I am not unhappy with the radio, but it is such a radical example of invasion by "The Phantom", that I had to share it with you all. Just a quick look over, because I am off out with the band now, but I knew things were awry when I spotted a battery holder neatly sited behind the back cover. 8-o Off with the back and whew, the tuning assembly is all there and working, but the wires from the tuning cap disappear under the chassis and I can just see a PCB! The rectifier and output valve are still there, but not much else on top. Interesting project or what? :beer:Steve.

Re: "Interesting" DAC90 project
A battery DAC90? Is this now a BAC90?
Only some valves missing puzzles me, unless the remainder are for show only. I can't wait to find out what's on the PCB - FM front end perhaps? I take it that the Phantom wasn't so kind as to leave the thing working for you. You really must put up a few photos of this! |
Re: "Interesting" DAC90 project
Hi Steve i have been looking for a DAC 90 myself and was going to bid on your set but was put off when i could see the battery box behind the back panel,any chance of a picture with the panel off.

Havent looked underneath yet. Set doesnt work, which is a shame considering the amount of work this "heretic" put in trying to update this nice radio.Obviously a very ancient crime, AM only with the rod aerial clinging to the back cover. Steve.

Looks a nightmare,what can the previous owner have been thinking of.

And a Ferrite Rod!

PS Only thought "The Phantom" was to be found at Woodseaves!

Re: "Interesting" DAC90 project
Wow. I bet you'll have a lot of fun trying to work out what the Phantom was trying to achieve.

Re: "Interesting" DAC90 project
Well, I think I may have been wrong about AM only and if there had been any chance that this might have worked, I wouldnt have ripped it all out, but with the original output transformer left in circuit and 500k volume pot, I fear not :-/ .Goodness knows what that board came out of, theres a slider switch on it going nowhere, so there no means of band changing anyway :beer:

Re: "Interesting" DAC90 project
All those beehives and the mustard caps suggest Philips?
|
Re: "Interesting" DAC90 project
That looks like vintage Philips, or at a pinch maybe a Grundig. I don't remember a Grundig with all those beehive trimmers

Re: "Interesting" DAC90 project
If you get stuck, i have a dac90 chassis somewhere, from memory it is complete apart from valves, o/p tx & dropper.
I had a portodyne princess that someone had "transistorised" using the guts from a roberts r200, looked like whoever did it did a reasonable job of it & it worked well. I ended up swapping the case for my cracked example, fitting the modified chassis to my damaged cabinet & fitting a small 9v psu gave it a new lease of life, i ended up swapping it for a rough prewar set.... :beer: Mark |
Re: "Interesting" DAC90 project
Thats an interesting looking old transistor chassis, if it comes up for scrap, could I put my name on it?
Thanks Dave. |
Re: "Interesting" DAC90 project
Yours if you want it Dave. :thumbsup:

Re: "Interesting" DAC90 project
Excellent, you have a PM.
That's what I like about this site, one man's junk is another's interesting trinket. Dave. |
Re: "Interesting" DAC90 project
I'm still hunting for the missing bits, mainly the two IF's and oscillator coils, maybe the tagboard too? :thumbsup:
|
Re: "Interesting" DAC90 project
Hi Steve, excuse my ignorance, but will the IFs and oscillator coils from a DAC10 work? I know the DAC90 and DAC90A/DAC10 are definitely not the same, but I have most of a DAC10 chassis going spare. If you can use any of it, you're welcome to it
