Marantz 7 pre-amp tube circuit module audio test

[@jackandamber]

I purchased one of these preamps on Ebay. They sent me the wrong transformer 220 volt. I finally got the correct transformer on Ebay 110 volts as I live in the USA. Do your research for the correct transformer. This preamp sounds INCREDIBLE !!!! I have heard a Merantz 7 and I can tell you this is the for real deal! I also own a Dynaco pas 3 preamp and this sounds much better and cleaner. You can not go wrong with this preamp for way under $100.00. I’m now going to mount all of it on a chassis with rca’s. Now who sings that song in this video??

[@rambacancha]

what is the output impedance in this preamp?, can you connect this preamp to a power amplifier like marantz 250.....I have one I connected to Marantz 250 and sounds terrible ...

[@bubakhungaricus3969]

Well, how does it sound in person?

[@diyhifi2632]

Hi kabayan. Is this preamp using 6z4 and 6n4 tubes. Power supply 150 0 150, 0-6.3 volts?

[@joelkine]

Yes it is kabayan. It does really sound great even with thise Chinese tubes. I still have 3 modules on hand for audition and whoever is interested. Cheers 🥂
