“Retro-EAR834p” - an EAR834p tube MM phono stage


























This is the third of these MM phono stages I have built and all for commission jobs. As an addition here a MC step-up stage was also built. The MC stage is the La Pacific single FET, battery driven stage and is seperate from the MM stage. The PS is external and uses a Hammond tranni. The EAR kits come with a PS board with HT and filament DC rectification and filtering. The HT is smoothed by a high voltage power FET. Works well. 

Looks smart on the stippled Hammond wood cheek chassis. With Tung-Sol and LinLai tubes sounds detailed and transparent and the new owner reports excellent bass. We are both happy with the result.

You have some really nice projects here. could you possibly share with me the connectors that you use for your external power supplies connecting to the amplifiers? I want to try that.

I simply use a large XLR connection.
