Default Re: VMARS RA17 product detector modification

Thanks guys.
The 8uf capacitor is definately required, as without it hums and motorboats.
I did add an extra 0.1uF decoupling, fitted inside the screened bfo compartment.
It's a neat mod, as only pins 5,6 and 7 require disturbing and can be accessed quite easily.
I didn't have an EK90 to hand, so I used the one from the harmonic generator and fitted an EH90 in its place.
Best wishes to you Al and everyone this Christmas.
Rob.
