Spooky and Hellraiser SMD 60W amps (Wolverine compatible IPS)

[Indiglo]

You should be fine using the spooky BOM, the transistors between the various boards are essentially the same, only the topology being different.
With no proper schematics and BOM can make it difficult for someone to gather enough information to populate the board.

 

[jwilhelm]

It looks like Q6/Q7 footprint is odd. Normally dual transistors have the bases on pin 2 and pin 5.

Ok I found what I used for infidel.
Q1 Q2 fjv992
Q3 Q12 Q13 fjv1845
Q4 Q5 HN1A01F dual
Q6 Q7 FMBM5401 dual
Q8 Q9 HN1C01F dual
Q10 2sa1419
Q11 2sc3649

Fmbm5401 has emiter in the middle.
There is also silk screen error r21 and r22 see post #659.

Thanks for the transistor list, extremely helpful.

As for the rest of the components caps and resistors I have a few questions,

With the capacitors I was thinking C4,C5 and C9 these https://www.mouser.co.uk/ProductDetail/KEMET/C1206C104K1RAC7867?qs=HwP6sGvP66Zs23oA/PYFtg==

Capacitor C3 this one https://www.mouser.co.uk/ProductDetail/KYOCERA-AVX/12063C225K4Z2A?qs=U/DGNQcZ28qtz%2BVpOZ%2Bu2Q==

C6 and C7 this type https://www.mouser.co.uk/ProductDetail/Vishay-Vitramon/VJ1206A101JXEAT?qs=RFK7ThnmtPvk1pY6DbPviw==

Which type would be the best to use for C2?

What wattage of resistors would be used? I've noticed the Spooky Bom specs 1/8w ones? As the pads for R20 is larger would this be higher wattage?

 

[chat72]

I bought from mouser and element14 and used whatever they have to offer.
For C
C3 C4 C5 C9 = x7r type your choices are fine.
C2 C6 C7 C0G type

For R
Small pad
I use mix of 0805 thin film and 0102 MELF. 0102 MELF type has higher wattage. You can find cheaper house brand from element 14.
Big pad I use 0204 MELF you can use 1206 film type.

 

[Chrisr3521]

Great thanks for that again much appreciated @chat72

Do you have a close up pic of your board?

 

[chat72]

I am using TH resistor for r16.

 

[jwilhelm]

Has anyone built the Spooky input? I see the simulation files and schematic call for a white LED for D8 and D9, but the BOM and layout list a red one.

 

[chat72]

I builted it but didn't work. I am not going to blame PCB just yet because I don't have time to debug it. It might be my fault somehow. I just leave it and do something else.

 

[jwilhelm]

I'm curious if the red LEDs in the input stage are causing your issues. It looks like the current drops to about half through the input stage in simulation with red LEDs.

 

[anatech]

The normal red LEDs have lower voltage drop, but are less noisy. Probably not by much.

 

[stocktrader200]

Wolverine can be used with a single output pair as long as supply stays below +- 45 volts.
To improve the design requires Mosfets and a dual balanced VAS stage.
Valery did some great work on this before he sadly passed.

 

[OmeEd]

Is there a schematic available of Valery's version with dual balanced VAS?

 

[kaliwraith]

I would like to build infidel with mini ef3. Anyone ordering boards / got boards to sell? is there an infidel 1.1?

 

[Chrisr3521]

I've got some mini ef-3 boards but might be cheaper ordering from JLC Pcb depending where you are in the world

Yeah, probably. JLC PCB is getting some errors with the gerbers. Looks like I need to rename the files. I'll document what works...

Infidel seems simplest to build so I'd like to find gerbers for that.

 

[chat72]

Infidel v1.0 gerber is on the first page. I don't think there is another version. Apart from silkscreen error, see#659, it works.

 

[kaliwraith]

Thanks Chat, I must be a bit dense, missed it... maybe got confused looking for symasui, which is not present. Will report back once I've got the boards ordered.

Seemed fine to me, just drag and drop the zip file to the relevant part of their home page, if you chose the slowest postage method it really brings the price down.

 

[kaliwraith]

Oh, I see, I needed to upload the entire zip from here as-is. I zipped up the gerbers directory and it was not happy with that.

Alternatively, maybe the linux zip program makes something nonstandard. Anyway, if you upload the entire .zip file provided by OS, it will work.
