Michael Tibes said:afaik it's a simple trsansformerless one opamp circuit, no surprises in the basic design. The secret ingredient is the opamp... It might be interesting to discuss the circuit and guess why the opamp suits the task so well or why it sounds so good. Maybe there is a suitable opamp availble nowadys? I don't have any confirmed information on the original opamps I only know that they are potted and like to explode once in a while.

Well..out of love & respect to George all I will tell you is that there is nothing "simple" about the design/circuit. And No its far from just a "simple one opamp design". The GML all discrete transistor class-A transformerless mic-pres are imho among the very best preamps if one is after a preamp that just amplifies the mic and source. I love them and has used them since ohh early 2000´s.
The same goes to the GML 8900 compressor seriesII..sadly Out of production for couple of years as I love that one. The GML 8900 can be looked at..as 3 compressors "in one" per side of the stereo unit. Many have had a hard time "understanding" the 8900. I never understood this. Its quite logical imho. Okay!.. Its a bit more complicated than a LA2A, 1176..but really not much. One hell of a compressor, that offers DRC that beats the living daylight out of anything elese imho.
His digital plugin DRCII is a GML 8900 on steroids.
Kind regards
Peter
