Re: Matsusada WA6-30N Manual

Had called them regarding cable and no luck, but didn't mention manual. Will do, thanks Jerry!

Matsusada WA6-30N Manual

I’m looking for a manual for my power supply, referenced in another thread:

viewtopic.php?f=11&t=12054

As noted in that thread, I have no manual for the I/O connections on the supply. It would be a yuge help if anybody could provide one for the WA series.

Thanks.

Re: A Bunch of Failures

Keep it running for an hour or so, should be hot to the touch, not just warm.

My pump kept improving noticeably after each such run for the first 3 I remember, note that I was starting off at about 40 microns and got to 10, somewhat different to your situation.

Re: A Bunch of Failures

Yes, I’m pretty sure John means to put a blank directly on the inlet and see how much sound it makes.

Re: Matsusada Power Supply Cable

Makes sense Richard.

Good news on the connector front, I found a Matsusada document detailing the different connections they use for power supplies. They have dimensions for each, which should enable identification.

Re: Matsusada Power Supply Cable

Power supply arrived. Been knocked out sick for the past week and haven't measured the length of the HV output tube yet. As Ian mentioned it's a sawtooth connection as looks to be a similar length to the pipe opening to contact in Rex's picture. I was taken aback by how far in the tube goes. The out...

Identifying coax connections etc

I found this webpage helpful for identifying different RF related connections, for coaxial cable and so on. See the attached pdf in case the website goes down.

Re: A Bunch of Failures

How do you know that all of the previous gauges were/are broken?
