Got my amp kit

Yo guys

So I recently ordered a 5f1 / 5f2a kit from a local guy - so it is quite ghetto, but just thought I'd let everyone know :D

There're no instructions, and a few parts that I don't know what they are, or how exactly they work, so expect lots of photos and hopefully a few less questions!!!

Cheers
Mike

good luck with the build; who was your local supplier??
iggy

A man named Karel Mars. A bit of a hassle to deal with - output tranny was supposed to have 4 and 16 ohm taps but it doesn't. Turnaround time was supposed to be 2 - 3 weeks, it took 7. Had to bug him a ton. But it was quite cheap so I am not complaining :P Without a cab, turned out to be $275. Most of the stuff was imported, as there's not much available, but I bought from one place, and the advice is worthwhile :)

Figured out all the parts now. Just need to get a soldering iron from a friend (Don't have one here at varsity) and make a mock up of where I will fit everything. Will post pics as soon as the lighting improves :D Overcast so not going to battle now.

Thanks
Mike

Heh, I guess you take what you can get in South Africa... sucks that it can't be as easy as here!

If you can post pictures as you go, that'd help a lot. :cool:

Good luck!

:D As we say here - "n Boer maak n plan".. As a country I see us as verrnacular. Even when I used to be into pc stuff, we make the do with what we have.

Will probably lend a decent lens for my camera from my buddy tomorrow so I can start it.

Basically it's a 5f1, switchable to 5f2, bright switch, and planning to be able to swap between a 6v6, 6l6 and 6550. To get the 16/18 watts I was hoping for, I'll need to run 4ohms, but hopefully I will be able to sort out the transformer soon.

Going to make a cab and head out of SA Pine, hopefully fingerjoint it. If that goes well I will make one out of Walnut and flamed Maple.

Thanks again ;)
Mike

Sounds fun!

I hope there'll be photos :smile:

Ok so I have been going through my bits.. Maybe I am a little confused here but they seem to not be the correct values..

2 x 10uF 450V caps

1 of these, 0.5uF, guessing it's for the speaker output

2 x 22uF 40V

2x 22uF 450V
http://i816.photobucket.com/albums/zz89/I34z1k/IMG_2444.jpg

470PF or 0.00047uF right? 350V.

Can anyone tell me what value these are?

SBE715P600V
223J 0707

Ok turns out that's 22uF 600V - those are right :D

That's it for caps, but check this :D

5Y3GT next to my 6550

And then the resistors

Now call me crazy, but are these caps like not even close for a 5F1?

Would this work?

1x Sprague Atom 16uF/475VDC TVA Axial Electrolytic Capacitor
2x Sprague Atom 8uF/450VDC TVA Axial Electrolytic Capacitor
1x Sprague Atom 25uF/50VDC TVA Axial Electrolytic Capacitor

"25uF/50VDC, .625" x .25". Replaces "Fender 25uF/25V" and lasts much longer."

Already got the speaker one for certain. Or am I confused?

Thanks guys :)

Ok chatted to the guy that supplied me.

He is still waiting on that and the speaker import wise. Knew about the speaker, but not the caps.

Cheers
Mike

Finally got everything. Assembly will start tomorrow. (Yes it actually took 3 months :/)

Anyone know how to implement an FX loop on one of these amps?

2 x 10uF 450V caps

1 of these, 0.5uF, guessing it's for the speaker output

2 x 22uF 40V

2x 22uF 450V


Hi Mike

Those values ought to work - the 10uF 240V will be okay in place of the 8uF filter caps in the original - probably even within tolerance expectations of original caps. Similarly the 22uF 450V will be in place of the 16uF in the original - again not much of an issue.

But by the looks of those radial caps and those old mica caps, it sure looks like parts there are hard to get

I'm picking that "0.5uF" could in fact be a .005uF/5nF Mica cap (really old-fashioned example of one) for the tone stack - (or at least it ought to be)

The 22uF 40V will be in place of the 25uF cathode bypass caps. No issue with using those

470PF or 0.00047uF right? 350V.

Can anyone tell me what value these are?

SBE715P600V
223J 0707

Ok turns out that's 22uF 600V - those are right :D

That's it for caps, but check this :D

Now call me crazy, but are these caps like not even close for a 5F1?

Yep that other mica cap will be the 450pF in place of the other (500pF) tone stack cap, and the orange drop (715P series) caps are 20nF (.02uF) for the 22nF/.022uF coupling caps. Again not a big issue really because tolerances of caps in traditional fender amps could have values that actually measure out by up to 20% either way from what they are supposedly rated at.

Yep that other mica cap will be the 450pF in place of the other (500pF) tone stack cap.

Ooops, I meant 470pF of course

Tx Tubeswell.. I am making it 5F2a switchable so seems that ancient cap is for that.. Wonder if I should get a new one in it's stead - what do you think?

Gonna Fedex these goodies :D Decided to go for 44uF on the first Filter? cap stage.

measure it ! if it's good run it, in the mean time order what you think you'd replace it with.

Its an old style mica cap, and they can last for several decades so its probably fine. But if you're worried about it, then order a modern backup
