Hi,
Due to Virus, my PC was down, so could not update you all.
I was not able to get ZTX550, so I am using BC557 as substitute.
IRFP240 and IRFP9240, pair was available for $6 (pair).

Hello Everybody!!
Merry Xmas & Happy New Year..
Sorry fo delay due to holidays, and parts availability.
Final Stage of F1 Amp
Now that I have a working F1 Amplifier.... Observed the following...
(I did not put Heat sink.)
MOSFET becomes Very very Hot.. (Q3 and Q4 Smokes with out heat sink)
Thick Heat sink with silicon paste and insulation is required.
Quality of sound is very good.. !
I will I have signed up with paypal, will mail details tomorrow...
Instead of ztx550, BC557 is used.
Attached is parts list I used. |

Hi there, I'm interested in a stereo set, could you forward images and let me have an idea of shipping costs to the UK?
Thanks |

Hi Suds,
:cop:
Post a price list please. Buys should be out in the open as far as prices are concerned. Let's keep things clean if we can.
Did Nelson approve of your buy?

Hi,
I had posted the Prices of DIY PCB's before..
This is DIY PCB F1 Clone means for DIY users, Not commercial.
I am not a commercial reseller or manufacturer.
I am also one of the DIYer.
Prices are as follows for F1 PCB's.
For one stereo Set PCB (2x Amp PCB's and 1 x Power PCB) $36 plus shipping ($21 onwards)
I cannot post images due to size (file is 2.5MB) I posted e-mail address.
Thanks

Hi suds,
Cool, all I know is what I can see in this thread. Many members might see things for the first time here, so a reposting of your pricing should almost be the first post in a thread. Somewhere near the top anyway.
If you post your pics on a server, you can link to them in a post. That's how members can get more than one photo per post in.

Yeah, so having just acquired used HornShoppe Horns read accolades about use of FW F1 w/them and came across this...
Wondering if there is any chance some F1 PCBs are laying about just waiting to be acquired:)
Any thoughts/help would be much appreciated. |

Wondering if anyone else had trouble here? |

Yes, that's an even better question than mine:)
Wonder how many used these boards (successfully) and if this is the right place to ask... |

Hi,
I have tested boards before making them on production ?
what problem you facing.. ?
can you scan and mail me both side images of boards.
I have checked against schematic from F1 Manual.
Have you soldered the components/ wires both sides , where they join top and bottom tracks ?
(My set of prototype boards are working fine.) need more inputs on what problem you are facing ? |

I do have suds' boards & finally got around to finishing soldering them up tonight (did the mini-A 1st)...
They are working fine for me.
I'll be posting a thread in the pass forum about it.
But if I had to bet, I'd bet on a 47 / 0.47 ohm resistor mixup... I found a BOM or 2 that had the decimal in the wrong place (or was illegible).
I worked up my own BOM based on all the info I could find.
There is the question of whether this offering meets the non-profit requirements for the use of the IP... At $100 USD for 2 full sets of boards shipped to US (total: 4 amp & 2 PS PCBs) covering alot of square inches & this single 2-set run/request, I'd think there is little or no profit for suds. Just the small run based on PCB area would probably be several times that price from ExpressPCB for example.
There are a couple minor issues with the boards, like somewhat small traces, small pads & small holes... But no biggie for sure & silk screening is correct & matches the BOM I was able to construct. |

cfcubed, you may have nailed it. I have not looked at these boards for awhile. I too forayed and built the F2 P2P.
The units were not drawing current, so source resistors are suspect. I may have gotten drain and source mixed up. |

Here's an export of that section of my BOM (amp resistors):
"R1-R4,R21,R22,R16" 221 OHM RES 221 OHM
"R5,R6" 562K OHM RES 562K OHM
"R7,R8" 392K OHM RES 392K OHM
"R9-R12, R27, R28" 1 OHM 3W x 12 RES 1 OHM 3W 5% V-D
"R13,R14" 1M OHM RES 1M OHM
R15 475 OHM RES 475 OHM
"R17,R18" 47 OHM 3W RES 47 OHM 3W 5% METAL OXIDE x 4
"R19,R25,R26" 1.5K OHM RES 1.5K OHM
R20 10k OHM RES 10K OHM
"R23,R24" 4.75k OHM RES 4.75K OHM
"P1,P2" 490-2983-ND 5k pot TRIMPOT CERM 5K OHM 12TRN TOP
"R29,R30" 0.47 OHM 3W RES .47 OHM 3W 5% METAL OXIDE x 4
Re: Drain & Souce - everything is oriented from the topside of the boards & again, I found the silkscreening dead accurate incl transistor orientation. But I printed out the schemactics & transistor datasheets to double-check all the important things...
It took me quite a bit to make up the full BOM (correlating the 2 or 3 F1 BOMs I could find w/F1 service manual) had to consider what I had on hand, stuff from eBay & Mouser & Digikey, etc. Par for the course though I guess....
Was able to come in < $400 complete by using alum (nice scrap?) plates & transfo off ebay (you know the ones.. Working fine for me tho).
Hopefully you have that F1 stuff laying around & can get it going sometime... I assume you've proofed the PS (like 24v per side?)
If you want more info just fire me a PM or something...
Good luck,
Chris
BTW, as suds said above, the boards rely on leads as VIAs, but just nicely filling the holes with solder from the bottom worked fine for me. |

Hello..
Yeh, I don't sell boards for living, they are for non profit.
I realized after boards arrived, traces are smaller but had made in large qty, to take price advantage.
There are no via , component lead act as via, (need to be soldered on both sides, fill solder).
( I have some more boards left.. )
Thanks for feed back.
currently working on other things..
( 5.1 channel Preamp with adjustable gain (Input preamp)
and digital volume control.. )
Thanks again..

I like a set of boards if they are still available (left, right and psu).

Chris,
The PS worked great, and stole it for my F2, so I need to rebuild one to continue on my F1 quest, or figure out how to use a borrowed bench supply. With the qouted personality of the amp and the F2's performance, I want to complete this at some point. Right now I am trying to get an F4 running. This all happens in small steps for me, usually none without some dumb*** mistake along the way.

Cool... I think I'll be done w/amps for a while after this F1 is done.... How many amps does one need? (rhetorical, let's not answer that:)

I hear you man for sure.... Spend a lot of time trying to make sure problems are avoided, but the problems could care less:)
Thank goodness for the Internets & all those sharing so much info...
Good luck! |

Let's be clear on this - I don't get excited about people making boards on a
not-for-profit basis, but I expect that they will do their own pc artwork.
My board artwork is copyrighted under international law.
These boards are lifted directly my own copyrighted artwork, omitting only
the copyright.
If you want to sell pc boards of anything I own, you must obtain permission,
and to date I have not granted permission to anyone, nor do I intend to.
