Tube Amp board question

[Zben3129]

Hi all,

I just went through the BOM for the P1, thought I had everything, made the order, and let out the sigh of relief that I had finally pulled the trigger on those tranny's. Crap. What am I gonna build it on??  I was wondering, If I took a block of wood, and put nails in it in the general array of the turretboard layout, epoxied the very bottoms of the nails for stability (not the tops where any connections would be made) and made sure nothing stuck out the bottom (not good to short to chassis with high voltages i presume), and was very careful soldering everything and making sure everything was good and connected, could I pull this off? I know it wouldn't be very sturdy, but I really just want to get this off the ground. If I need to buy a turretboard and redo this later, so be it. I just want to give my wallet a break for now


Any thoughts?

Are nails good for soldering?
I wouldn't do that, decent board is not expensive at all, you can get large board from mcMaster carr for less than 15$ shipped and it's sufficient for two amps.

Thanks!

How hard is it to install turrets?

[caress]

it shouldn't be too tough... especially compared with wiring your amp on a board with nails...   probably not the best idea, especially if you're excited about the project... in my experience, it's usually a good idea to wait and do the project the better way than to start it just for the sake of getting it off the ground.

You can use terminal strips.  They're pretty cheap and easy to get a hold of.  Here are a couple that I've done that way:

P1-Extreme


18-Watt


The terminal strips I used in the 18watt have 12 solder terminals and mounting eyes on each end.  The work well for doing a turret board layout without a turret board.  The P1EX is just my own layout with standard terminal strips.  A board w/ nails is doable, but I wouldn't recommend it.  You could even do an eyelet board using brass eyelets from a fabric store and 1/16" phenolic perf board from radio shack.  I would do that long before wood.

you could try with eyelets, too. Cheaper than turrets, little easier to install, and IMO "work" just as good.

Ooh I'm liking those terminal strips

Any info on where to pick some up?



Thanks

I picked mine up at a local electronics place.  I got the last 6 that they had and promptly broke 2 by shutting the bag in the door.   

I have seen them around on the "intraweb", but I don't remember where.  They are really, really nice to have.  I've got to find some more.

http://www.hoffmanamps.com sells terminal strips under the "Board Building" section.  I've bought a few for my projects and they work well.  Be wary that at least one lug is the mounting piece as well and will be grounded to the chassis.

For terminal strips try:

http://www.oselectronics.com/ose_p113.htm

or

http://www.tubesandmore.com/

(look under terminal strips or terminal boards - you get 5 in a pkg.  Also their catalog is great)

or

http://www.elexp.com/con_0800.htm

They come 10 per bag - see the last one on the page (6 lugs, 2 sep mounting lugs)


So there are some options - shop around, remember to compare shipping as well as the price. 

Just finished an P1-HO - I bought the kit because when I priced it for parting out, it was about the same and not significantly more.   It came with eyelets, which are a little of the prob if you have to stick a bunch of stuff into the hole.  It may not all go into the hole - take for example the UFR Diodes, they have thicker wire then the regular 1n4007 types, well, some if it didn't fit.
