hi Kooka,


sorry for my mistake,

its was 0~9V & 18~0~18V.

Hi pchw & all,

I collect two pcs of Similar type as Blue RS Isolate power transformers for DAC use already.

pri -----0~110 X2.
Sec----0~9 X2

AND

pri -----0~110 X2.
Sec----0~18 X2

All were 20W

It will enough for support simple kit consumption , although later U upgrade to full balance version+ USB, power supply still enough to provide a stable envoirment for dac.!

very resonable price, USD 26 per pair.

probably postage added USD 4 will OK, So added USD 30 will get one pair more of isolate power transformers.

Hope all user will lover it. Photos will post to U tomorrow.

Now is HK time 0300hrs AM.

thx

110v is no good for me. In NZ, we can take 220-240V. Can you give us the RS part number so that I can look for same grade power supply here.

hi all,

this was RS similar type balance winding isolated power transformer.

U can see it seperate into 4 chamber on the bobbin. Use seperate chamber isolate transformer better to prevent noise feed from pri to sec.


That why I don''t like triode transformer although they said they were isolate. Because I thought they not real isolate!


Hi samL,


pri was 2X110V, series connect can use in 0~220V.

is it OK for U?

USD 26 per pair.

postage will only increase USD 4.

take a look of them.

thx

thomas

An externally hosted image should be here but it was not working when we last tested it.
