Voltage dividers for 14 pin PMT base

Post by Sesselmann » 23 May 2015, 10:36

Hi Guys,

I just had a batch of circuit boards made up to fit the popular 14 pin Diheptal PMT sockets that sell on eBay for around $12. Soldering resistors directly on these sockets is a pain, as they are really designed to fit a board.

The one pictured below is made up with all 1.2 M Ohm resistors and 10 nf capacitors and it performs nicely. I have made facility to fit a trim pot between the cathode - grid and D1 if required, alternatively it can just be fitted with a 2R between the grid and D1.

If anyone is interested in some of these boards, either raw or with components soldered, just send me a PM.

Steven, I'd be interested in some of these circuit boards (soldered with surface mounted components desired). Could you give me a price? I'd like about 4 of the circuit boards. I'm also wanting to order a SHV-SHV and SHV-BNC cable. Thanks! Rob Tayloe <robsmoto@yahoo.com> or <rob.tayloe@gmail.com>

Hi Rob,

The board pictured above is an old version, I have a newer better version in stock, I will email you the details.

I had typo in email address initially in my profile. I have updated the profile with a correct address. I also responded to earlier email receipt for recent order. Thanks. (for some reason PM isn't working - sorry to take forum bandwidth0
