John Warren Posted January 2, 2020 Share Posted January 2, 2020 Recently swapped the OEM power supply transformer in an LK72A with a Heyboer replacement. The Heyboer is a well made component. Removing the bell is a bit tricky but it can be done without causing mechanical strain in the lead wires. The leads are tinned, multi-strand and the insulating jacket material very tough. Excellent results are achievable. This is a great little amp, very quiet! http://www.northreadingeng.com/Audio/group/viewtopic.php?f=4&t=8&p=29#p29 1 Quote Link to comment Share on other sites More sharing options...
NOSValves Posted January 14, 2020 Share Posted January 14, 2020 John, Yup Heyboer does a nice job on many vintage transformer replacements. Most of the Scott they worked with me to iron out the specs many years ago. Quote Link to comment Share on other sites More sharing options...
