For the same price You get this one:
Talema 0160P1-2-030 (160 VA, 2x30 V, 2.67 A)
You would need 2 pieces for two boards.
I always enjoy big transformers, but not stressed.
Any ideas regarding this two transformers?

Block LF 14/15 has 2x 15 . And it is humming a little bit, I got them at the moment. If You hold them in Your hands the hum is tolerable. If You press them to a table, its not tolerable.
Did I miss something?

Hello,
I'm thinking to use two 2x24V 30VA R-Core or toroid transformer, one for each channel.
30W 220V R Core Transformer Output 24V 24V | eBay
a toroidal transformer from Toroidy.pl that have about the same price.
What do you think about?
Ciao

The voltage is now 24 V, You are right, at the beginning of the discussion it was 30 V.
This one fits too:
Block RKD 80/2x24
It seems impossible to show that ebay link??
Only the overview.

I found in my spare parts box a Talema 30VA transformer 2x 25 V / 0.6 A
(RS0030P1-2-025K)
I powered it on and it is a lot!!! more silent as the Block transformer.
I will give it a try.

My transformers are also humming alot :-(
Even tried to DC-couple them, but without any difference.

Forget the 24 v rating on these ebay r cores.
Figure more like 28 / 28 v
I have bought a few and the guys that sell them have broken or cheap DVM,s and can't measure or give accurate specs to save their life..,.

AVWERK: Transformers are usually higher voltage than what they suggest... since many are measured with 100% load (internal loss of some voltage) and when you run less current, you get higher voltage... This is quite common with transformers to my knowledge, and i have seen it more often than the other way. If the voltage is less then expected, then i would say there is a trouble 🙂
U are not alone
Hello Guys,
first i feel like i have to apologize for a thing i am not
guilty of.
Everybody who is not happy with his new noisy roommate,
feel free to contact BLOCK, but, please behave !
They did not believe me.
"Crap" is a harsh offense, but, in fact, they are close to it.
Today a closer friend told me about another example with
different voltage....
Those replacements i've got from them are not exactly
quiet either, but, as i wrote earlyer, build in a box with some
care, they should not do any harm.
Please understand the fact i can not afford sending those
replacements around the world without refunding what i have
to spend to DHL.
Yesterday i tried to check out what alternative we could just
swap without any pain.
Sadly, the spec-sheets i found were not really helpfull, because
most of them are for a whole line of t-formers and i have to get
a closer look....
Stay tuned.

Hello Robert,
i did read it.
If you might read my previous post you'll possibly
understand my position.
Those Blocks i got are noticeably better than those of
batch #308031 (written in white on the underside).
If you &/or somebody else decide to go for exchange.
Send me all the money you got and hope for the best.
But keep in mind, those you will get are NOT completely
noiseless. (but really much better than the previous ones)
This is my last attempt on those Blockers....
