Hi,
I am searching for information about the EMI RS61 Electron Tube Microphone Preamplifier.
I am sure you have seen this crazy ebay auction where it is mentioned:
http://www.ebay.de/itm/EMI-RS61-Electron-Tube-Microphone-Preamplifier-Pair-with-Fairchild-PSU-V72-U47-/330719730922?pt=LH_DefaultDomain_0&hash=item4d006e9cea
;D
Is this really a microphone pre amp?
The reason I am interested is, somebody told me that this amp is based on Mullard EF37a tubes, I found some of them in NOS condition for small amount of money. This tube is pretty famous for low noise operation...so I want to build a mic pre with it.
Is there any schematic or further information about this EMI RS61 available for free?
best regards 8)
