Info on EMT A 144.7 Channelstrip and EMT 245 Reverb ?

[mo's taverne]

Hi,

an old Radio guy offered me some very nice EMT gem's for a LOW price on a fair last saturday. And i'm very thrilled to get some info's on those.

2x EMT A 114.7 Channelstrips with mic pre
1x EMT 245 digital Reverb unit

as it is really hard to find infos on the channelstrips on the net, i come here to ask for more information.

What quality are the Channelstrips in terms of recording audio with them?
What price is average for the A 114.7 and the 245 (great condition)?
Can i get some shematics to solder audio connectors to the Channelstrips?

has anyone infos about these units?
Thank you much in advance!
