I´ve seen the different pinning.The BD139/140 are rated at 1.5A or?Notice that BD139/140 have different pinning.I have some D44H11 and D45H11 if you want to test.
Yes I could try the D44H11 and D45H11,what´s the price?
Ok,2SB649 can handle 1.5A so can BD139/140 can I use them instead?Please change Q3/Q4 to 2SB649, Q13/Q14 to 2SD669.
MPSA42 and 92 I have at home but they are to weak?
As Q1/Q11 i use MJL21193/94 they should be enough.Am I right?

maybe MPSW42/92 is affordable too.
cheers

Hi
MPSW42/92 is a little bit risky.....
sorry
Coffin
Ok I´ll try BD139/140...MPSW42/92 is a little bit risky.....
Dear Coffin,
Are the sample PCBs still available ?
I am rebuilding an Electrocompaniet Ampliwire II and it needs a regulated voltage of ±39 V in the drive section. I have a voltage of around ±47 V available after the filtering capacitors. Is the differential voltage high enough for the Mini Regulator ? The current requirement is around 100 mA.
Regards,

Hi Coffin,
I got the boards. They look great. Thanks a lot.
Is the BOM ( http://circulator.bravehost.com/minireg.htm) up to date or something has been changed?
Also, I noticed there is a new design called the Evolution 2004 regulator http://circulator.bravehost.com/EVOLUTION_reg.htm
Are you offering free samples for this design as well?
Regards
