Psvane has made a number of improvements over the standard 845.
The Psvane 845B eliminates the mica bridge which braces the plate structure against the top of glass envelop by having strong posts that are anchored in the valve base and run up on both sides. This prevents the plate structure from movement and rattles and more importantly prevents internal vibration, which is the key to why this valve sounds so much better than the standard 845.
845B is direct-heated type thorium tungsten cathode triode which has a special leaded anode for more consistent operating temperature.
Psvane have increased the distance by 35mm between anode and grid leading wires which improve the insulation and reduces the medium loss of stem glass .This prevents the issue of stem blown and air leak from stem that older items suffered from.
The Psvane 845B has a special base made of Bronze also improves the valve heat dissipation.
These 845B have 1250v plate rating with max anode current rating of 120 m/A .The valves are factory matched and selected and then retested here in the UK By Watford Valves. We select these in Dual matched pairs on anode current and g/M to ensure you get the best quality. Each valves comes individually serial numbered and with its own full test certificate.
These are available in matched pairs only and are priced individually.
