I'll remind you ..... that's for the 48 KV transformer in the sub station that feeds AC to your entire neighborhood...... remember?😉
I would rather use a bigger heat sink than a smaller with fans!. HI-Fi gears do not mix with fans at all!😀
well. thats the same amount of heatsink as i'm using for a pair of F5turbo monoblocks🙂
i guess they are around 20-25cm x 120cm?🙂

it all depends on the power "class". 🙂 You will have to use fans eventually...if you keep on increasing power output.
yeah, ok, bought for BA2, some time ago(too long) 😀
fins are 70mm
it will do either 4 pieces of 300 x 250mm, or 2 pieces of 300x 500
but now I dont know
could be fun to build a 500watt balanced monster 😛
but expencive
not quite that much, but I do have 2 pieces of 2kwatt trafos
but wattage is far over rated with only 2x 38Vac
but with balanced, I think it might be home again 😀
if I increase power...I would increase heat sinks!😉 Beside I do not use class A amplifiers!
about optimos
this amplifier are not meant to be played at low volume.it is not intended for home use.besides the casing where not that good.but in terms of professional use you could count on it.heatsink are sufficient enough even using an L bracket.only two pairs of lateral mosfet where used.may be wondering why?...thats the importance of using vi limiter keeping the operation of the output device at safety region and less number of output.
this amp. is stable even at 0 ohms.and possess a soft clipping action reducing the burning of high frequency drivers.and has a protection at input just in case higher voltage where accidentally feed to this amp.even if there is a small disadvantages implementing it ,still small price to pay than having a blown output transistor😀
and how about sound?well many of the members here will testify how good it is...🙂

this should hopefully turn into some kind of 'hybrid' preamp 😀
oh what, and mounted inside my new preamp box

Nice super structure so far. The dark brown stuff... It looks like a premium grade of Masonite. Yes, but sturdier?
originally pressured paper and oil
now a days I think they might use epoxy too
but Im not sure
some have claimed it to be the 'best sounding' isolator there is
well, at least its strong
and I just happened to have some of it 😛
