toroid and r-core - Page 2

Telstar · 06:13 PM

I think i could pickup a R-core transformer and compare it to my favourite potted toroid from Nuvotem/Talema.
This curiosity must be satisfied. For low power amplifiers (headphones or 2W max) they seem a valid option.
I can use ears and some basic measurements equipment - a 5,5 digits true rms DMM and a 50Mhz scope. If nothing else, this would be a good learning experience.

Edit: comparing with a screened and potted toroid would be interesting indeed.

These are the two transformers that I will be able to compare in the next few weeks, attached to AMB's sigma22 PSU:

2) http://www.selectronic.fr/catalog/pr...ory/172666500/

Sorry for the long link from RS

I used both, now if I can afford all my buildings with R-Core.

Telstar, I'm looking forward to read your impressions on the two transformers.
