Default Re: KG1 and 16K9 substitutes

Have you read the excellent article by Euan MacKenzie in Radio Bygones #134 Cristmas 2011 or the excellent article by Gary Tempest in Radiophile Summer 2000?

Repairs and restorations of the AVO Mk I & II are discussed there and the diodes are discussed in detail.

Soft recovery diodes like the BYW96E (now obsolete) are recommended there - the equivalent to BYW96E is BYT78 according to Vishay.
