Please contact us to discuss ordering.

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)

Amtrans Carbon Film AMRG Series

MKIII Resistors (PRP Audio Grade Metal Film)

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

$35.00 (per amplifier) 

PRP Audio Grade Metal Film

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 (Carbon Film & Carbon Composition)

This option includes a mix of Carbon Films and Carbon Composition Resistors by Kamaya and TE Connectivity / Holsworthy. Fantastic Sounding Carbon Film and Carbon Composition resistors. These really add a WOW factor to the sonics of the amplifier!   

$40.00 (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) 

Capacitor Options for the MKIII

MKIII Capacitors (Amtrans AMCY Golden Black)

The best sounding caps ever for the MKIII. Aluminum Foil Paper in Oil. Imported from Japan! (.1 and .22uF @ 630V / Aluminum Foil Paper Oil) 

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

MKIII Binding Post Upgrade

Due to limited space in the chassis opening I can only install 3 binding posts per amplifier chassis. This means that one of the 4, 8 or 16 Ohm outputs will be unavailable. Generally I omit the 16 Ohm taps but the choice of which one to eliminate is up to you, just let me know. The binding posts will accept banana plugs or bare wire. This is a great upgrade for the MKIII.

$30.00 (per amplifier)
