Here’s a super clean Audio Prism Mantissa LINESTAGE preamp with separate power supply.
Audio Prism was bought by Levinson and rebadged as Red Rose,
And here’s some cut and paste blather from the interweb:
The preamp has five line inputs and a switched non-buffered Tape Out. Operating modes are Standby, Mute, On and -1.5dB. The last will reduce both channels volume by 1.5dB to provide finer steps in control. Two independent 23 position stepped ladder volume controls with discreet resistors provide attenuation with 3dB steps per position. The preamp is muted for 30 seconds after power is applied or when switched out of Standby position to either the On or -1.5dB position. Mute will defeat the output or restore immediately if the 30 second power on or Standby delay has occurred. A front panel bi-color LED indicates red for Mute, green un-Muted. A rear panel switch allowed floating the chassis or connecting it to circuit/signal ground to obtain the lowest signal hum.

And here’s what Master tech, Herb Ward, said about the preamp:
The controls and switches were cleaned and treated with Caig Deoxit The tube sockets were checked and found to be tight and clean. The former owner reports that the tubes ( Sovtek ) are all like new as he purchased a new set of tubes thinking that the intermittent noises coming from his speakers were produced by his preamp. It turned out that his power amp was the problem. The chassis was cleaned and a considerable amount of dust balls were removed ( indicates that the preamp was well ventilated ) The preamp was bench tested for a day, all line level inputs and outputs were tested, and found to meet specs.

Since getting the pre back from Herb, I listened to it for one week, 8-10 hours/day. Herb will warranty his work for 6 months, excluding tubes, return shipping and insurance.
Extraordinary preamp. I’ll include a generic power cord.
I’ll ship this in a heavy duty double box that will weigh 30 pounds. Don’t ask me for a shipping price to your far flung island country or East Nowheresville. Do you own home work and know that I will charge you what the shipping company of your choice charges me. If you can’t afford the shipping and insurance, you can’t afford this component, right?
Paypal users add 3.1% to the final price, including shipping and insurance fees. Paypal users with funds that originate in a overseas bank, add 4.1 % to the total.

Please ask any and all questions. Nothing to hide here, just good clean hifi fun.
The fall selling season is beginning. In the next few weeks, I’ll be listing lots of cool components, including the matching Audio Prism Debut amp
