Needs GZ34 as a Bridge Rectifier diode is a bodge up!

Perhaps the mains transformer has a faulty 5 volts section!

Seller has SC22 to match with this power amp.

The seller (Russell Merridew) is a nice chap to deal with.

Not even mentioning the bypassed rectifier in the listing (although finding plenty of space for copy-and-pasted ‘liquid midrange’ comments) cause me to wonder about the seller’s priorities.
