Default quad303 pcb for renovation

I had some quad303 pcb's with me that's made to replace the original ones. Anyone interested can email me at

tony_chan_cf@email.com

They are modified to use PNP-NPN for the outputs and TO-022 for the drivers.

I think your Quad 303 deserve more than this, found on Ebay @ US$25 + US$10 shipping

Default a newer version

I had some new boards for Quad303 in which I have added :

1. some mounting holes for new system builders.
2. Traces modified to take MJL's PNP+NPN. If you find appropiate
output pairs, you can snug them in and give a try. They can be
soldered onto the board directly (ideal for new system builders)
3. Some components relocate to spread better among available
space
