Multiply the capacitor values by 10. Since you're working with CFB opamps the Rf and Rg values should remain as written.

You may have to work on the compensation values for the ALC.

Arrow Ultra low THD Oscillator PCB order list.

Hello,

For the 10kHz oscillator PCB, if i order 10 boards to Pcbcart the total price
will be 120 (including Fedex shipping).
So, for end user the price would be : 120/10 + shipping to end user.
For 1 PCB, the shipping from France would be about 5.5 to USA (priority letter).
So for USA user the total price would be 12+5.5=17.5 ~ 23.5USD.

The PCB specifications is 100x160mm, 2 layers, one top layer silkscreen, 2 varnish mask, metalized holes, gold finish RoHs.

If at least 10 DIYers are interested , i can take the order.
Please send me private message and i will make a list with interested people.
Before to proceed to order, i will ask you paypal a payment of each personnal orders.
(I will don't make any money to do that , but i won't to loose mine !)


Frex.

I'm interested in one. Frex, you might want to start a wiki GB list, it's easier to keep updated without cluttering the thread.
