need h/h ma 100 schematic

[stevo!]

anyone out there have a schematic for an old h/h ma 100 ?,as i have
one with a burnt component i need to identify in order yo repair.would be
grateful for any help!

[STEWART]

Hi stevo! I have schematics for most h/h amps inc the ma100 pa amp. Let me know the component number of the burnt part, then i can give you the value.

hi,Stewart the component in question is "R32" on power amp board.
Thanks for your reply....stevo!

[vintagekiki]

R32 = 0R1 = 0.1Ω / 6w

[STEWART]

Hi Stevo,
Sorry about the late post (work).
As vintagekiki has given you the correct value.
The resistor and many other parts are available for your h/h from CPC/FARNELL.
The order code for your vitreous enamel resistor is RE04097.
Hope this helps.
Stewart.

Yes,Stewart,your info.was a good help!many thanks.....Stevo!

[STEWART]

hi stevo, yes there were two versions of the power amp board, looks like you have the early one! R32=100R R8=27K R11=1K all 1/2 watt, (s=speaker) Q1=TIP29C Q2=TIP30C Q3=BC204B Q4=BC207B Q5=BC204B Q6=TIP29C Q7=TIP30C output pair 2N3773HG. stewart.

Don't suppose anyone has a schematic for an HH TPA100 or TPA100D?

Hi Guys,
Does anybody have a Schematic for a HH SM200 powered mixer Please ?
Thanks Steve.

Thanks Steve.

Steve -I do not have a schematic for this model of amp -I only received the MA 100 schematic. I believe that you could probably get one from Maj Electronics (they also have a few spares left for this particular model).
Maj sell a service manual for this model which will contain the circuit diagrams, unfortunately it will cost you £9.50 - -sent electronically. A lot of these amps use very similar circuits -so sometimes a schematic from another model can assist. If you get stuck with a particular component send me a photo and I'll see if I can assist in identifying it.

Thanks Joh.

Thanks John,
I will check out Maj Electronics as you suggest and see how I get on.
