LMNC Cloney 2025 batch

LMNC Cloney 2025 batch

this page is only for the Cloney batch from 2025, called “LMNC”version from the “look mum no computer” build

feel free to check my other VCS3/Cloney/SynthiA/Synthey pages The Cloney Project VCS3 Clone to get an idea how an assembled Cloney was built.

I built 7 Cloney and few other EMS Clones.

capacitors have footprint for 5-7.5mm or 2.5thru 5mm.

which means 2 “holes” are still connected with a trace (yellow box)

Issue 9a

here comes an update for the Construction Manual Part I - mechanical work -

Obviously there is a mistake on the fibreboard. Check also the attached photograph and screenshot.

The lower small hole for the tapping screw seems to be on a very low position. Normally it has to be in a distance of 28 mm to the lower edge. A builder reported a problem with this hole.
After checking the last batch here in the workshop the hole is at 10 mm. So I checked the CAD data and changed the hole position to the 10 mm. The preview shows the hole will match to the upper center hole on the connection panel.

Very cool! So there is not really a problem. This way the third countersunk M4 screw to fix the wooden bar to the connection panel is obsolete.

IMPORTANT:
The center hole on the wooden bar should not be drilled by 4 mm. Because the fibreboard screw will then stay loosely.
So drill the center hole on the wooden bar with a 3 mm drill (0.12") and no more.

you should cover the via holes with a tape to avoid a electrical contact to the germanium transistors.

wiring - cables

improvement

Mogami offer tiny shielded cables - 1 Core and 2 Core.

you need for the Cloney Potentiometers at few places 3 different cable types:

unshielded cable 0.25-0.5mm

shielded coax cable single core

shielded coax cable 2 core (like microphone cable but much smaller)

you get in the full kit of the Cloney RG157/RG158/RG159 cable for example, this is a shielded coax single core cable and works fine.

but it´s easier for me to use other cables like the mogami W2784 , its only 1.8mm diameter.

general info

R 297, R 298 und R299 sind Koppelwiderstände (1/4 W) für die Leistungsstufe der NF Amps. Zur Reduzierung des Klirrfaktors und Verbesserung des Ansprechverhaltens der beiden Germanium Transistoren bei sehr geringen Lautstärken. Können aber auch weggelassen werden, ohne dass jemandem der Unterschied im normalen Musiker Umgang mit dem Gerät auffallen würde.

 

general parts info

Und R305, ebenfalls 47 R, ist ja als Alternative zum optionalen PR23 Trimmer

 

general

C80 in X pcb is 1nF capacitor
