Default Yet another F5 building log

I hope you don t mind another vanila F5 building log thread

My goal is to eventually build 4 channels to drive my speakers in biamping topology.

For now I have received the F5 and the generic PSU boards from the DIY store, and I am now working on the component list.

So far I have located the F5 parts. I would appreciate it if you had a look at my list

Thanks a lot. I hope I have some more news very soon

Dimitri

6L6 will stalk you until its done. Fair warning from experience.

Bring it on! Hopefully I can give back a little from what I've received in my own build thread.

It s good to see people following on such projects

Hopefully next week I will order some more stuff... for now, it s just planning (I love to hate that phase... reading and more reading...)

Still trying to decide on transformer size (thinking of 1KVA) and find a relevant good vendor.

For now, I have decided to get the 5U 400mm Dissipante from HIFI2000 (to accomodate for possible turbing of the project ).

To be honest I like the 1+2 approach as well... really classy and good WAF... and the price is quite nice too... hmm....

Are you thinking of a 1K VA transformer for 2 channels or 4? It's complete and utter overkill for only 2 channels. Very good for 4.

Dont mind at all new F5 tread go for it

About traffos I got 1 KvA on mine with 20 and 24 V taps now I wish I had a few more volts

I had a bit of trubles with traffos as poor construction caused same hum
I sent one back and it was resin dipped and most probably the tape over it was retightened no more hum from that.

At the time this is what mighty Zen sugested on MY F5 tread

Oh my god my head almost exploded trying to read this...

1KVA overkill for two channels? I am running a 100mA phono with dual 160VA toroids... And yes there is audible difference from smaller ones...

To be honest I was thinking 1KVA per channel.... Perhaps I will also get a 600VA one and compare. I still have to find some decent built ones though...
