Cool thread @noromance and thanks for sharing the modification- for those who don’t understand how tight things are near tube sockets on a Croft - you can see a photo of a Croft RIAA - RS ( single chassis ) phono stage in my Poverty Bay virtual system page - Glen is a wizard and builds great sounding gear
Installed bulk foil resistors in phono amp
I installed four of these Vishay Z-Foil (TX2575) in my phono preamp - the loading and series input resistors on the first triode. Considerable improvement in clarity, image stability and perception of speed. Highly recommended upgrade. PartsConnexion. 4 for $65.
