In zeer goede staat! ( paar plekjes maar absoluut niks dramatisch)
100% werkend.
Serienummer 009
Met “Nature” switch als extra ( originele ) optie. - zie info onderaan.

Deze amp kan met VERSCHILLENDE SOORTEN BUIZEN werken!!!!

Daarnaast kan hij op de abnormal input schakelen tussen buizen en Fet- zie info onderaan.

Werkt met 6L6, 5881, EL34, 6CA7, KT66, KT77, KT88, 6550, en 6V6

Deze point to point buizen versterker is door absolute top tech genieën ontwikkeld om de BESTE VERSTERKER VAN DE WERELD te worden !!! ( Google is your friend )
En ik moet zeggen dat dat streven aardig realistisch bleek, het is absolute topklasse, sowieso de meest veelzijdige amp ooit! En de klanken staan allemaal als een huis, je zit de eerste uren met je kin op de grond, echt waanzinnig mooi!!!
Ondanks dat het een moderne amp is, zijn alle klanken volledig in het “vintage-territory” SUPER warm, sprankelend, organisch, en hij gaat van ultra cleane fender “chime” tot waanzinnig rijke harmonische overdrive/ distortion, het “randje distortion gebied” is echt ongelofelijk!!
De eind versterking blijft tot volume-stand 2 ongeveer totaal compressie-loos, maar vanaf 2 schakelt de buizen compressie in, die dan steeds meer word en echt heerlijk “pompt/ ademt”.
De ingebouwde “powersuck” is ook fantastisch! hij zorgt dat bij elke stap omlaag voor een zeer subtiele boost in de “hoog informatie” van je geluid, echt geniaal! het resultaat is dat het geluid gewoon hetzelfde blijft klinken bij attenuatie!
Hij kostte rond de 7000,- euro. ze zijn ( daarom?) niet lang daarna gestopt met het bouwen ervan, dus uiteindelijk zijn ze maar in kleine oplage gebouwd.

Ik kijk even wat er geboden word, en hij gaat alleen weg als het bod me “verleid”
M.a.w. handelaars maken geen kans helaas .. ik heb niks tegen handelaars overigens!

THE TONE!
Front panel controls:

NORMAL INPUT : used for clean sounds to light overdrive
ABNORMAL INPUT: used for overdrive sounds
FET-TUBE SWITCH: selects the type of distortion obtained from Abnormal input – where the FET option lets the input tube be driven without the rectifier action of an overloaded control grid resulting in a sound with a little less buzz, slightly cleaner tone than ordinary tube overdrive. TUBE: is an all tube structure for a classic tone.
VOLUME: sets the gain of the preamp
MIDDLE: works as normal midrange control except it’s affected by FOCUS
BASS: works as bass control except it’s affected by
FOCUS: a four position rotary switch which selects two different center frequencies for the T-filter, with or without a mild treble boost. The tones are GREEN with or without treble boost and PURPLE with or without treble boost
TONE BALANCE: this controls the balance between bass and treble, work similar to most treble-knobs on other amps.
TREBLE: controls treble
BOOST: sets how much level-boost is obtained when boost switch is pressed
PRESENCE: controls the treble response of power amp – works by removing feedback at high frequencies
MASTER: controls output level – works by attenuating level at power-amp input.

NATURE SWITCH (4-POSITION ROTARY SWITCH) This switch has four positions controlling effects loop level and brightness of amp.
There are two level options. One for low-level effects, driven by a 9V supply, and one for line level effects, like tape echoes and certain studio or rack gear.
Each level option has two tones available one bright lead and one softer with extended bass response. The bright lead option is considered normal. The setting of this switch will affect the settings of tone controls. Use the softer setting for getting tremendous bass.

5 SPEAKER OUTPUTS ( 2×4 ohm, 2×8 ohm, 1×16 ohm )
4 POSITION “POWER SUCK” SWITCH to get great tone with lower volume.

EXTRA INFO:

The Mad Professor CS40 is a high-end, hand-built, all-tube amplifier designed by Björn "Mad Professor" Juhl and built by Jukka "Bukka" Mönkkönen. It's known for its versatility, exceptional tone, and ability to handle high-powered distorted tones with clarity.

The CS40 is not based on vintage designs focused on distortion-free tones, but rather is designed to produce a range of distorted tones, from "clean" to fully saturated, with clarity and a tight low-end.

Hand-built and Point-to-Point Wired:
The CS40 is meticulously hand-built using point-to-point wiring, a construction method known for its potential to optimize tone and signal paths.

Versatile Tone Shaping:
It offers multiple gain stages, including preamp and power amp distortion, and various controls for treble response and a foot-switchable boost.

Power Amp Saturation:
A unique "POWERSUCK" switch allows for driving the power amp to achieve fat, compressed tones at lower volumes.

Bias Flexibility:
The amp accommodates various power tubes like 6L6, EL34, KT77, and others, with an adjustable bias system for fine-tuning.
Designed for High Gain:

Unlike many classic amps, the CS40 is designed to handle high-powered distorted tones with clarity and a tight low-end.
Inspired by Repair Experience:

The design was influenced by Björn Juhl's experience repairing and modifying classic amps, incorporating elements he found desirable.

High-Quality Components:
Mad Professor emphasizes the use of over-rated components for reliable and safe operation.

Handcrafted in Finland:
The CS40 is built in Finland, reflecting a long tradition of Scandinavian craftsmanship in electronics and music
