Can I somehow get 2x24V out of this transformer?

Hi everyone,
I´ve got two MXR Digital Delays ripped off for using the chassis for the G1176 project. I would like to use the power trafos of the MXRs as well. So here is my (maybe stupid) question. Can I get 2x24V out of this power transformer? Here are some specs:

nope, that seems to be a 2x15V transformer (unless it's grossly overspec'ed)

and you really need an absolute minimum of 2x24V - preferably 2x30V.

Hi Jacob,
thx for your reply. Since I don´t know what is going on in all these electronical parts, it is nice to have people like you, who explain complex things to people like me. So I have to look for a 2x30 V Power Transformer for the G1176.

BTW: I have two Telefunken Dolby A Units Model 360 with I/O Transformers. The Output Tranny is a 1:2 step up. Can I use this for the G1176? Here are some photos.

Yes, I think that should be possible..

Hello Kubi,
thats interesting. What do I have to do? Do I have to change the power supply on the 1176 board?

Bernd,

Are these the 3U blue panel MXR DDLs?  I have one that is not working and am looking to also expand its memory.  You didn't happen to keep any of the boards from these, did you?  If so, I would be interested in buying them for spares/expansion.  PM me if you're interested in selling.

Thanks,
A P
If it is to be, it is up to me.

Hi Darius,
I read some threads about voltage doubler and dl the schemo. I haven´t started the G1176s yet. I´m waiting for the boards from Gustav to come. May I ask you more details (about which Caps and Diodes to take and maybe how to exactly connect the telefunken output trafos) when I start the soldering? Thx a lot so far. I saved this thread to HD, if you don´t mind.
Regards
Bernd

Darius,
would you have a closer look at the schemo in the first post?

Hi Darius,
I´ve already done a search for some nice torroids. I really appreciate your help. Thx a lot. Thx, Jacob.
