I'm considering building an F1 but Im having problems sourcing a good heatsinked case. The one that is easiest for me to get hold of is the Pesante series from Hifi2000. I'm unsure if they have good enough heatsinks for this beats though. Any thoughts?
I'm thinking about it too...
In other posts I red you have to multiply the thermal resistance for the power to dissipate (in Watt) to have the delta temperature ABOVE room temperature.
I think model 04/300 should be fine...

An externally hosted image should be here but it was not working when we last tested it.

I am using the HIFI2000 4U/300 for my F5 which requires 0.6C/W per transistor - there are 2 per channel. It hovers around 65C at 1.6A bias. I was running 1.7A and I could only touch them for a second or two.
Not sure of the requirements of the F1 - hope this helps.

Ok, it seems the specs provided are ok:
0.31*(62*2)=38.44° above room temperature (maybe 25° in your home).
F1 dissipates 100W per channel (F5, instead, 124W, 62 per transistor), so I think a 3U can be used.
Am I right?

F5 o.m. said:
"At 1.3 amps per channel, you will see idle heat dissipation of 62 watts. To keep the temperature rise of the heat sink to 20 deg C. above the ambient temperature, you will want a heat sink rated at about .6 deg C./watt for each transistor. An example of this would be a chunk of fi nned aluminum, with a series of 2” fi ns attached to an 8” by 6” base. You will need two per channel."
F1 o.m said:
"Place the amplifier in a well-ventilated location, as it draws 200 watts during operation and requires as much opportunity to cool itself as possible."
I'm doing something wrong but I can't understand what...
perhaps trying to build an amplifier? 😀
F1 manual
"The voltage across R27 – R30 is approximately 0.60 volts DC, and this
figure sets the bias for the gain stages, which is slightly less than 2 amps
per side, 4 amps total."
I would definitely not go below a 4U size - and with slightly less than 2A bias per channel probably go for the 400mm. If depth is a concern then go for the 5U/300.
