Hello. I'm new to the forum and to DIY audio. I recently discovered the work of Nelson Pass through a friend. Mr Pass, thanks for all you're doing!
Now I'm building a (Nelson Pass' Mosfet) Citation 12 to pair with my Sonus Faber Minima (4.5" woofer, low sensitivity, not-so-easy load - kill my Naim Nait 5i on the low freqs).
As I don't own a preamplifier yet I'm wondering whether the input sensitivity of the Citation 12 will allow for direct connection to a source (CD, DAC...) or through a no-gain buffer like the B1.
If the above is possible and before I build the buffer/preamp can I use a pot (maybe 25K log?) between the source and the power amp to regulate the volume or will it somehow compromise the output signal of the source?
Thanks in advance.
Cristian

hello friends,
I bought a plate amp citaion 12 on Ebay, the seller is not sure about it. I wonder if the transistor Q4 should be glued to the heatsink for thermal control?
Already many thanks for the information

MOD ZEN Sorry, what was the site? My English is bad, I can not understand everything that is written in the original text
In the link I provided, there is a simple scheme, only wanted to know if Q4 must be thermally connected to the heat sink ...High Quality IRFP240 Push Pull Audio Power Amplifier Kit Based on Citation 12 | eBay
An externally hosted image should be here but it was not working when we last tested it.
