MKIII Resistors (Amtrans Carbon Film AMRG Series) 

Made to take the place of the legendary Riken Ohm Carbon Film resistors, these are simply the best sounding resistors you can put in the MKIII. These are non-magnetic, encapsulated in a black anodized aluminium case, potted in a highly thermally conductive resin, brass end caps, and have gold-plated oxygen-free copper leads.

NOTE: subject to availability, may require additional lead time to acquire these components.

$110.00 - (per amplifier)

MKIII Resistors (PRP Audio Grade Metal Film)

Nice sounding, audio specific, 1% metal film resistors.

$35.00 (per amplifier) 

MKIII Resistors (Takman Carbon Film & Metal Film Mix)

Beautiful sounding audio specific carbon film and metal film resistors.  NOTE: all values needed to populate the entire PCB may not be available, equivalent substitutes may be necessary for some locations.

$65.00 (per amplifier) 

MKIII Resistors (Carbon Film Mix)

Excellent sounding carbon film resistors.  Brands like Kiwame, Yageo, KOA Speer.

NOTE: similar but equivalent substitutes may be necessary for some locations.

$65.00 (per amplifier) 

MKIII Resistors (Carbon Film & Metal Film Mix)

A combination of carbon film and metal film resistors. Carbon films in the audio path, metal films in the power circuit.  NOTE: actual colors will vary, images are representative samples only.

$25.00 (per amplifier) 

MKIII Resistors (High Grade Metal Film) 

This option is a mix of High Grade Metal Film Resistors by Dale, PRP and TE Connectivity / Holsworthy. 

$40.00 (per amplifier) 

MKIII Capacitors (Amtrans AMCS  "Golden SQ")

Incredible classic sounding caps for the MKIII. Aluminum Foil Paper in Squalane Oil. Imported from Japan! (.22uF & .1uF @ 630V / Aluminum Foil Paper Oil) 

$200.00 (per amplifier) 

MKIII Capacitors (V-Cap ODAM)

V-Cap ODAM Reference Grade Capacitors (Oil Damped Advanced Metalized)  A serious upgrade, these  are a "top-of-the-line" capacitor offering for the MKIII. (.1 and .22uF @ 630V / Aluminum Foil Paper Oil) . Made in USA

"realistic timbre/textures, tremendous instrument separation, remarkable layering and imaging, accurate leading edges of instrument notes, incredible low-end slam/thrust, and the absence of any discernible sonic imprint"

$180.00 (per amplifier) 

MKIII Capacitors (V-Cap CuTF Copper Foil and Fluoropolymer Film Audio Capacitors )

Way more than a "top-of-the-line" capacitor offering for the ST-70. The V-Cap CuTF (Copper Foil Fluoropolymer Film) series capacitor was inspired by Chris VenHaus's obsession to tap into that special "magic" found in the soul of tube driven music. Too often, inadequate quality of passive components strip the color from the performance, or add colorations of their own. The Elite series caps from V-Cap will transport  you to new levels of "audio perfection".

The (4) .1uF coupling caps are V-Cap CuTF, the (2) .047uF bypass caps are V-Cap TONE (Copper Foil in Oil). Made in USA.
