COLORSOUND: The Yellow Hybrid OC140 Tone Bender by Jake Rothman, 0.15" Vero Layout

All the details are listed in the previous post - this is a 0.15" version of the yellow Colorsound Hybrid Tone Bender.  

I did the previous layout on standard size vero, and after using 0.15" vero and tag board on a lot of builds recently, it just seems very tiny now, so I did another layout on a larger scale.

YELLOW HYBRID COLORSOUND TONE BENDER - 0.15" VERO LAYOUT

note:  the exact value of the zener diode at the time of posting this unknown

On the bench, waiting for an OC140 to arrive in the mail.  I've built another on regular vero with an AC127 (which sounds great).

Not exactly as per the the layout above, as I moved a couple of things around a little to fit more comfortably.  I'm also going to try a 47n cap in the tone section instead of 33n - 47n is found in earlier versions.

• 0.15" vero
• 1W carbon film resistors
• The orange caps are Philips
• 500pf styroflex caps instead of 470pf ceramics
• OA7 germanium diode
• Standard MKT caps in grey and white
• Q1, AT462 which is similar to a BC107
• Q2, BC109C
• Q3, will be an OC140 - once it arrives in the post
• Added 100ohm resistor to combine with a 220uf for power filtering, and a diode for polarity protection
