Description
I am offering a pair of upgraded Coincident Frankenstein MK III mono amplifiers with following upgrades:
- Very Low hours tubes, NOS Sylvania (6EM7), Mullard GZ97, original 300B
- Tuning and upgrading by Audiomagic.nl for superior sound and stability.
These are amplifiers for the connoisseur and their modification history starting with a Tektron design is well documented (on the web). The Audiomagic.nl upgrades push them again to the next level (cost over 1300,-€). For the content regarding the upgrades contact me (pls only seriously interested audiophile fellows who seek after a definitive amplification solution and appreciate the „upgrade philosophy“).
The amplifiers require a matching speaker impedance SET profile. I used them with speakers from 89 to 99dB sensitivity with formidable results. Speaker Impedance is however key.
In the high-end audio (pricing) world these represent a bargain. RELEVANT and RELIABLE information with respect to their matching characteristics and performance can be found here:
https://www.high-endaudio.com/RC-Frankenstein.html
Excellent condition, some minor cosmetic flaws on the mirrored polished surface.
Many thanks for looking!
