Aleph 3 Toroid

Mark A. Gulbrandsen · 22nd February 2004, 05:12 PM

Can someone reccomend a good toroid for for buildinhg an Aleph 3. I did a search and could not come up with anything definate. I was thinking about an Avel Lindberg but the lowest secondary available is 25+25 volts in the 500 VA range...... Otherwise I suppose I'll go to Victoria again.

Thanks,
Mark

Hi Mark
Transformer. The Brand Toroid (Swedish) has in their standard range 500VA from 9+9 V and uppwards i 3V steps. They are
made for 230V primary but they also have a plant in Brazil who may be manufacturing for US standard. We use a custommade
300VA from the Brazil plant in a stepmotor drive system and they seem to be of good quality except for solderability on secodary leads.
If You want the real thing i´ve got 500 and 1000VA E-cores
in 15+15 and 35+35V.

What about Plitron. Isn't it what is originally in Aleph3?

Mark A. Gulbrandsen · 22nd February 2004, 08:05 PM

I'm not sure what was in the original 3, could ahve been Plitron I suppose, or Avel. Yes, Plitron does have an 18+18 or 20+20 500 VA toroid but I've got to wonder how many months I'd have to wait for it....... The smallest Avel has is 25+25 volts in a 500VA. Was just curious if anyone has an off the shelf toroid available in the lower voltages. I would prefer to stick with a toroid if possible.

Go with Victoria Magnetics! As you know, they'll wind exactly what you want.

Avel Lindbergs are a real value and I've had no complaint with mine. Burn the extra volts in a CRC filter.

I have had good results with Victoria Magnetics so far. It doesn't take him too long to get a transformer made to custom specs and shipped out.
