A few surprises turned up in the yard today ,
an Altec lansing graphic eq , I imagine made sometime is the late 70s
I took a look inside and it was all gyrator based (no inductors), balanced in and out but transformerless ,
I didnt have any use for it so I took the mains transformers off to keep for project usage ,
One is your typical low voltage EI made by Peerless , the other is a quite nice Avel Lindberg heavily sheilded 15va toroid , 2x15v .
The other thing I found ,which presumably came from the same person was an old 70's style live mixer , ITAM London 10/4
I removed the end panel to see what was inside and low and behold , 10X Beyerdynamic 'peanut' mic input transformers , TR/BV351001061
Also another two of the same Avel Lindberg Toroids , 2x12v and 2x20v models .
I might return tomorrow and remove the limiters and maybe a few channel PCB's , but I cant take the frame .

I feel a bit sad now about to butcher the thing , maybe I should give Ted Fletcher shout and find out if its of any historical interest to him ,
It has 4 band eq and by the looks a direct out ,pre fader and mixbus returns , The PCB layout looks good , thick traces on FRP boards so easy to repair .
What I dont take tomorrow will surely be sent off to the crusher ,
The picture below is not the actual unit . Its almost identical to the Alice 828 .
