this image is 800 pixels wide, save to see full size I bought this excellent preamplifier recently on eBay. Internally it reminds me of Glen Croft's stuff from the UK
with cover removed. This case is very sturdy and superbly finished
Here with 12AX7 valves removed. excellent quality connections at rear, make a very tight fit with my RCA sockets. Notice twin outputs to power amp. I connect this to both my Sony TA-N7 (V-FET) and Syren class A
the single 6X4 (EZ90) rectifier uses a silicon damper ring (supplied as standard by YS-Audio) The three Tesla ECC83s are shown without aluminium tube covers
A great looking power supply runs down the left.
Connection wiring detail. I will be writing much more about this preamp over the next few months. It is very highly recommended Designer email address ysaudio@hknet.com
