Chassis wiring methods

Post by JJH0906 »

Have any of you amp builders have a preference of how you wire the components of the chassis? I come from more of a circuit board background but they seem sort of impractical for amp wiring.

So that leaves point-to-point and turret boards. Any opinions, advantages/disadvantages, etc?

Please share!

If you make your own turret boards you can get most of the wiring layout advantages of true Point to point as on terminal strips.

Of course removing and trying out different circuit components is easier with turrets.

Generic turret boards can be purchased on eBay for very little money. I have found they are generally versatile enough to build close to tested layouts. You can always drill and add a turret or two if needed. Remember, the G10 or FR4 board debris is carcinogenic. Once in your lungs, it never leaves. If you are drilling or cutting such boards, use a good mask or respirator and vacuum at the same time. For this reason, it is worth the money to just buy the pre-configured board you want. I find building on a board is easier than point to point. There is, however, nothing at all wrong with PTP, except it tends to look like heck when you are done.

What I like about using a turret board is that I can take a fine line Sharpie and draw all the parts on it before I build it. Alcohol on a rag or q-tip makes a good eraser.

I can't see why circuit boards wouldn't fit, as long as you care about analog requirements - in term of grounding, especially... :?:

Not necessarily. If you start building around sockets, instead of aligning tagboards on the middle of ths chassis - in some turretboard inspiration - you can complete pretty clean circuits.

I'd recommend having a look at Aaron "xtian" L.'s (amongst others) builds, if you're looking for some creative board layouts, though ... 8)

PtP has the advantage of shorter lead lengths, and works best for simpler circuits (i.e. a Fender Champ-level amp). It can be a bear to modify or repair, depending on the layout and which component you need to change.

Board-based is usually easier to build, easier to tweak, and easier to repair - particularly on multi-tube preamps, etc.
