The Don Audio GSSL transformer at about £40 would also do the job. Its 9V secondary can be used to make a dc heater supply for those who prefer it.
this might be considered a thread hi-jack but worth a shot:
Do you have any experience with that particular Don Audio power transformer? (220V AC, 9V AC, 5Vac)
I'm trying to help a friend of a friend in mechanically quieting down an RS.124 type compressor that has a particularly mechanically noisy EI type power transformer.
Options are limited because we need more than the usual 6V3 heater due to running heaters DC with enough margin for the regulator drop out hence...
Anyway, some torroids I've tried radiated horrendous fields so am hoping this baby is good to go for the job.
As you were gentlemen.
