Thomas Henry VCF-1 on Stripboard |
|
|
Here, Thomas Henry VCF-1 layout on Stripboard, design with LochMaster :
NB:
Stripboard = H25SR050 (50x100mm)
Q1,Q2 = 2SA798
OTA's 2xCA3080 = LM13700
IC3 = TL074 pins have been reassigned according specific stripboard design ( see Sheet_0001-1.jpg, Sheet_0002-1.jpg )

Thomas Henry VCF-1 layout on Stripboard rev.1 :
- reduced connections on the backside
- space for different trimmers pinouts
- GND route optimization
Stripboard: 63.5x100mm - 2.5x4 inch
Also a version for SSM2220 and MAT03 dual matched transistor

@Jaba
I have not built yet. I checked several times the circuit routes.
Anyway, I attached Lockmaster files so you can check yourself the circuit routes.
In Lockmaster, almost all of the components have in their properties tab, links to datasheet, forums URL's, suppliers URL's etc.
If you find something wrong, just post here.
- Finaly, version with matched 2N2906. Tempco install .... here

Hi Nardu,
I started putting together this VCF, following your layout for the 2SA798 version;
not finished yet, some parts missing
I think I found a little mistake: in the lower part of the board, at the right of IC1, R5 goes from a ground line to ... nothing, i.e. R5 is connected to a strip which has no other connection.
the same seems to appear in all of the layouts
another detail: aren't the hand matched transistors 2N3906 ?
I hope this can be useful
thank you again for sharing your work |

@Jaba - Thanks for your revision !
There is a duplicate for R5, (... lost in space ! , ) . Just remove it, see here. ( don't affect the circuit ! ). Valid for all other layouts.
Below, the Thomas Henry VCF-1 2SA798 layout on Stripboard rev.2 :
- remove the R5 duplicate

I don't understand the question, please reformulate, even in Italian.
