I'm sorry, I was trying to help.
60 seconds?
"A rough estimate for the diode bridge power dissipation would be 3 times load current times 0.75V per diode per channel. Factor of three needed because we have to correct for the non-sinusoidal current through the transformer secondary."
Roughly a minute, more or less.
Remember now why I hadn't been active here for the last 7 years...

hey guys , < newbie at electronics here , but learning . i'm gathering the stuff for my f5 and really want a front switch and want it to be attractive .
i've read about others using this switch BULGIN|MP0045/1E2BL012|SWITCH, PUSHBUTTON, DPDT-2CO, | Newark.com rated at 3a @250v , which i'd really like to use , but wondering if it might be marginal if even acceptable to direct switch the ac for an f5 .
thanx in advance

Lots of European companies do this (Ayon comes to mind), the trick is to mount it sideways. It anyway needs just one finger 
I put mine on the backplate. Just leave it on all the time, and switch it from the mains outlet. Some of my P2P ones don't even have a switch.
The trouble with a switch on the front plate is that either you have to have a thin plate, or recess the mount so the switch will actually clip correctly. I tried valiantly and then decided to move it to the back.
Some amps have a retro-style rotary power switch. That's really cool too.

The only problem with a thread like that is there are many appropriate parts, especially in the PSU...
However, a 'parts' thread that explains how to choose the right pieces would be really beneficial - is that what you had in mind?
I'll start with another question, where did you get those toroids?great looking toroids
anyone like the idea of a new F5 thread
F5, parts only ?
maybe someone else want to jumpstart it ?
Regards,
Hi there
Part tread be quite good Idea
I have posted pictures of heat sinks trafos and have quite few bits to sell
Only way to get the good stuff is in Bulk.
I have posted pictures on a Holco resistor for sale tread
I now have a batch of Futaba 0.47 but it is almost gone so just let me know
