SPL Dynamic D5s

[dips1982]

Hi, im picking up a SPL Dynamics D5s this weekend, which is need of repair.
Does anyone have a schematic and a manual for this Amp?

Many thanks 🙂

I don't think so, but... its like any other amp
see what is know, what failed, something like fets... remove them if they are
and see if you can power the amp up to see parts of the circuit work (or not)

Does anyone know what IC's are on the driver board? ive found pictures on the forum, but it only has 2 ic's, on mine there is 4

Post the photo with the driver card.

I had it with the IC's missing. Also seen that C6 is missing too

 

[Perry Babin]

The 4 missing ICs are:

IR21844S or IRS21844S

Either will work. I don't have the value of C6 but I'll see if I can find a junk board to check it on.

 

[Perry Babin]

On a 2-IC driver board (which should be the same for C6), I measure about 1200pf. This may be a critical value because it may help determine the operating frequency of the amplifier. I'd suggest that you order both the 1000 and 1200pf capacitors if you have to order parts.

If someone else has a similar board and can measure the value (or has more definitive information), please post that information.

For reference, the meter actually read 1.187nF. New 1000pf capacitors read 1.040-1.050nF.

Thanks Perry, I bought the Amp off ebay and opened it up to parts all missing out of it. I have a schematic diagram which SPL Dynamics sent me. But not the schematic for the driver board.
Luckily I have 5x IR21844SPBF.

Does anyone know the value of R30 on the driver board?

 

[SPLing]

R30 = 330R

Thank you

Im looking to get some inductors for this amp because there missing out of the amp, been cut out for some reason.
L201 - 47uH

What type of inductor would this? High frequency?

 

[Perry Babin]

These aren't critical. The following should work if it's the right size.
