Nice mm phono preamp 42 2101a realistic vintage refurbished. Either of my updated realistic units are being reviewed and compared to much higher priced units and are blowing them away.. check my feedback. 
if they don't floor you in cost/performance simply pay the return shipping for a refund.
 If you have a stock working 42-2101a or 42-2109 I can give you a discount of $25 if you ship it to me. that's about all there are worth un-restored.

Refurbished/updated: new high hour electrolytic long life caps in the power supply.. fast avalanche diodes, new updated power supply, new metal oxide resistors placed in the signal path. All the old ceramics have been replaced with poly film. The two yellow caps are mylar, glued down. 
Cardas solder & silver hook up wire used in the path. older silver plated copper rca cleaned up and sound good. Vpci cleaner/protectent used throughout. Wall wart external power supply 120vac to 12vac: that supplies the unit with its correct voltage, so don't plug any thing else into other than the 11 to 12 vac... 

If you want to return it for any reason just pay the shipping back for a refund.(pay pal can take a couple days)
I will support these months or years later. If you have any problems simply pay the shipping and I can look into them cheaply. not much goes wrong with them...

 Email me and please wait for my response, some times it takes me a couple days to reply.

free ship to conus only, overseas to pay shipping.
thank you

'I have this unit and a Hagerman Labs Bugle unit that costs more than $200. Your upgraded Realistic is better. I'm not saying that it's a better bang for the buck, I'm saying that it's just flat out better no matter what each unit costs. Great job! '

'Buy one of this guy's Realistic phono preamps with confidence! Awesome!'

'I'm speechless. A+++! I need two more!'

'Absolutely perfect! Thank you very much, friend!'

' It’s ridiculously great. I read the stories, didn’t believe it but I had to try it. It really sounds great and I already like it than my other phono stages that I have spent much life money on '

I’m totally happy with it, yours really opens everything up...Everything just sounds cleaner. Thanks for taking the time to improve these great little preamps.
