Re: 455 bad HV multiplier


Hi Guillermo - I researched that solution and found it to be too problematic. The 455 module also contains the CRT grid drive circuitry with a fair number of components. The space under the HV supply shield is limited so the obvious solution is to build a functional replica. It's a lot of work and time to do but very satisfying to save these beautiful 455 and 465M's. While most Tek lovers favor the 465 series I hate to see otherwise good scopes going to the scrappers. -Arden
