Testing Power Transformer Vintage Stereo Receivers

using this power block to protect and run vintage Marantz 2010 stereo power amp, Sony tape deck, Sony CD player and Pioneer PL-512 turntable. upgraded to this power block for extra safety on my electronics. will buy again to pair with a 4-10 Classic 50 guitar amp and accessories and a 100w Fender Bassman head and speaker rig. rugged quality, nice long cord, easy read lights. plug and play.

The MM7025 replaced a vintage power amplifier and gave new life to my dedicated stereo system. I have both analogue and digital sources, a PrimaLuna tubed preamplifier and B&W 702 S2 floor standing speakers, and this Marantz has proved to be a fundamental link in this chain. It leans a little to the warm side (which I like) and improved the sound of my speakers, with tight bass, very sweet highs, and transparent voices. At this prices level, I can't imagine anything better. 100% recommended.

Pretty good system. Only think the power transformer is expensive.

Killer quality and sound. It definitely widens the stereo field a bit. The transformer button wont be for everyone. I tried it on the 2 track and didnt like it, but gave it a go on the bass buss and yeah dude big time.

A lot less expensive than most computer interfaces and great if you only need stereo out from your computer. The sound is decent and it's transformer-coupled so you'll never have to deal with hum.

Best solution for indoor power supply but could have put the transformer at the end not in the middle.

I use this for testing my vintage cameras when I receive them (I'm addicted!) -- good balance of color, especially with electronic flash and daylight, good medium ISO value, lots of latitude.

Use these for running lavs receivers into a mixer/recorder. No problems, but you have to be aware that it doesnt work for some devices depending on mono/stereo issues. For example this doesnt work to run a Sennheiser G4 RX unit into a single XLR input- that requires a stereo mini to split XLR channels.

Perfect replacement chord for some stereo receivers; in my case an RS 700 Yamaha receiver. Also works for some Fender guitar amplifiers. Did the job perfectly.

I use this along with the DC 2 - DC Camera Power Converter to set up wireless speakers systems using Sennheiser body pack style transmitters and receivers. This power supply was originally designed for video camera battery charging but when used with the DC 2 Power Converter, you can create AC power to your transmitters and receivers instead of needing batteries or always wondering if your rechargeable battery is charged. This investment to my company was WELL worth the money! After 15 years of running speaker cables, taping down walk ways, taping over door ways and worrying about cable damage from being stepping on, heavy carts rolling over, getting pinched in doorways etc, I never have to worry about that again! I run all my systems now wirelessly with ease and convenience!
