Maybe BF245C or BF545C, or a BF245B (or BF545B) with reduced source resistor (about 390 ohm), or even a BF245A or BF545A with no source resistor at all.
Merci Marcel, i found cpl of BF256C...in a small shop in France, Now Fairchild/On semiconductor recommendation for replacement is the J111

Elektor preamp SSM2220 & SSM2210

Hi,

For sales SSM2220 & SSM2210 (DIP-8) they fit for the PCB above and they are the best available replacement for MAT02 & MAT03 Dual Transistors.
I bought the PMI in 1991 from Spoerle Electronic a German distributor se at the DATA Code.If you buy more than 12 pair I will not charge 4% PayPal fee. Sales only NPN & PNP pairs. I ask for 3,50€/piece plus shipping from Finland + 4% PayPal fees. Contact me if you are interested.

Elektor top of the range phono stage

Hi I built the elektor top of the range preamp for a friend back in 1988 and have since inheritied it. Its a great build if I say so myself except that I was always suspicious that the phono section gain is too high even when adjusted via the sil switches. Its tight but distorts on vinyl material with a lot of content. I can post a copy of the phono stage which used a MAT02-h differential stage coupled to a an OP07 opamp gain and RIAA stage. Can anyone help or has anyone ever encountered this same problem? Do I simply reduce the value of the opamp feedback resistor and alter the emitter current of the Mat02-h input stage? It was originally designed primarily as a high quality moving coil stage but could also be used with mm with only one MAT02-h array which is what I have.Thanks in anticipation. I have all three copied of the magazine article which were kindly sent to me by Elektor. Normally you would have to subscribe. So just a tip if anyone is in the same boat without a diagram.
