Yes the myriad of little caps on the right on the camco are the bus caps high and low. The ones on the left bottom are the mains reservoir caps for the SMPSU.
I dont suppose it matters if they're small if the SMPSU is high enough frequency! Camco vortex 6 will do 6600W into 1 ohm in parallel mono or 4 ohm bridge. |

LCR electronics were very local to where I live, they had two workshops, one of them burnt down......

LCR caps were always great fire starters

A couple of oldies, A late HH MA150 and an early MA100
Note the additional 'soft start' circuit(also converted to IEC inlet) which seems to work well.
Powered by these(RCA 2n3773)
The best part of these amps(apart from the sound obviously)!!
Apart from a few crackly pots both these amps work perfectly although the earlier MA100 does run slightly hotter than the later 150 but it also sounds sweeter, they're also suprisingly loud!!

From an ETD 59 Core?
Be serious!
With alot of hard, I obtained 4400Watts of Pure Power from an ETD 59 core, on mine Resonant mode SMPS.
3500 Watts continuous from ETD 59 yes, is believable, but 6000Watts, regarding amplifier and SMPS randament,means around 7200-7500 Watts from the power supply stage.
Also EMI filters are rated for 16 Amps, and power cable looks to be 2,5mm section, usable till 4 Kw. Edited by DjLeco - 23 December 2010 at 12:55am |

ahh .. wow.
Now, that is NICE! ... got to be right up there with the Peavey IPR stuff in terms of production engineering. Cooling layout is good, someone thinking "out of the box" there ... few too many relays, but, very nice layout .. thats a neat amp! I think they could have offered a lot more in that little DSP than just two filters, but I suspect thats a marketing decision rather than a technical limitation. You can just see their custom drive chips to the left of the two main output heatsinks .. from reading their blurb, they are a custom ASIC from TI ... you don't go that route unless you are planning on making a LOT of them ... and it helps keep the competition from copying them :) Interestingly, the DSP area appears to have been auto-routed .. quite unusual to see much autorouted layout on audio gear .. |

What do you think all those SMT resistors and leaded poly caps are underneath the speaker terminals are? Looks like it may be part of the output LPF? Not sure why there are all those resistors. |

I suspect they are the output Zobel network, you can't get very big SMT resistors, and they obviously preferred 50 SMT resistors to 1 hand inserted leaded device ... 50 SMTs will have been cheaper both in component count and assembly costs.

I allways wondered why HH never added an extra output stage,and made it a stereo (2x100w) amp.there was allways plently of room to have done it.....especially in the S130 slave,which was mostly fresh air inside!

Be seeing you.
