Darling amp plate voltage

[mylesmf]

Hi everyone,

I'm about to start building the 1626 Darling amp as described here;
http://www.geocities.com/TimesSquare/1965/darling.html

However I notice that the plate voltage is specified as 265v whereas on the Duncanamp tube locator page the maximum plate voltage is specified as 250v.

Is the 15v a small enough amount that it can be safely ignored, does the amp work better with a increase in voltage or does the extra 15v fall into a voltage black hole?
(I've certainly had a few projects fall into a variety of black holes in the past).

Or am I completely mis-interpreting the whole thing?
Any info greatly appreciated,

Myles

Yes, you are forgetting the cathode bias voltage so the 265V plate voltage should be just fine. I have seen and heard a bunch of these and they sound very very good. I would recommend you consider the dc darling as well - it is even better.

Hi,
I was given a DIY Darling amp some years ago by a friend who has left the country and is not contactable. Its a fantastic sounding amp with only 3/4 watts, but sounds very big. I would like to know if anyone has the schematics and also what the nos. are on the driver tubes? My driver tubes are quite old but have no nos. imprinted on them. Can anyone tell me what nos. they are? Any help will be deeply appreciated.

kindly,

Henry

Hi Henry,
There is information all over the place for the Darling and DC Darling. Have you tried googling?

Here is a link to the Darling page:
http://www.geocities.com/TimesSquare/1965/darling.html

The driver in a darling whether dc or ac coupled is usually an 8532 and the output tube a 1626. These are both old US industrial types and are fairly common here last time I checked. May not be the case in your neck of the woods.

I would contact Jim McShane (on diyaudio) and see if he can help you secure the required replacements.

Thanks Kevin,

Yes, how silly of me...I googled and found really useful info on some pages. Strange though...my darling has a rectifying tube (5y3) while I noticed most Darlings built by others use a silicon diaode for rectifying... any difference in the sound quality?...

cheers and thanks again,

Henry

I think the tube rectifier is the nicer/more deluxe way to go, in terms of sound though if properly executed they should be about the same.

I am about to build my 1st tube amp & a Darling I am about to build. I can not find a schematic with a tube rectified version. Does anyone know were to locate one or have a schematic of a adjusted PS for one of the published schematics..? I much prefer tube rectification on my tube amps, plus I have LOTS of 5y3. Thanks..

Do you know how to use PSUDII? You can make your own power supply using the 5Y3...

Where can I down load & or purchase this program..? It would be nice to have.
