Default Video already explained how to calculate..so...you will know

using the simple method...it works for my hot environment...may be good for your place during summertime.... and will be an overkill during the winter....average temperature here is 29 degrées celsius.... during winter drop to 22-24 degrées celsius.

Default I have found, from the other forum mainly, some guys

that are not "that skilled"... they where evaluated by the questions they have made.... then i realise i should explain details to help them to assemble.

Here you have the first video.... i do think we gonna have two or three in total.

1 - Tips and tricks about MKIII Hx components - YouTube

From time to time you may hear strange things in my videos...this is because i am human and sometimes i do mistakes (half of the time will be better to say)

regards,

Carlos

simple and small question: the velleman 4700 speaker protection circuit, is that "strong enough" for this amp? since it can churn out almost 500W per channel (in some cases )... and if not,do i just replace the relays with more heavy duty ones? or is there another solution?

Default I do not know...send me the schematic

sometimes only the relay...sometimes other modifications are needed.

Carlos

The circuit is good but you will almost certainly need to replace the relays. For 500W i'd say look at 30A car relays - anything else will probably just weld themselves closed.

Default Heatsinks for MJE15033 & MJE15030

Greetings,

Does anyone know of a heatsink which matches the profile Alex drew for MJE15033 & MJE15033. I've been looking at heatsinks for TO-220 cases and I can only find the stamped, "wrap-around" style which fit on the board. The nice extruded ones are all too wide.

-Byron
