Correct Size Knock Out Hole Punches

[ZeusMC]

Hi Guys

The chassis hole diameter required by tube sockets varies with the socket size and whether the socket is mounted inside the chassis or outside of it, as some sockets are stepped while others have a constant diameter cylinder. You should take some measurements from the sockets you have,  from drawings ff those you intend to use.

Have fun

" mounted inside the chassis or outside of it " Yes I realised that, after a bit more research a little while from when  I made my original post. I asked as intending to buy Chinese even though have to wait a week or so for them to turn up, have bakelite sockets and metal frames. Ebay UK item number 203593328614   and 321001703678 it gives the sizes of sockets. I've not decided whether to fit them inside or outside of the chassis. Is the difference only cosmetic or is there a reason to fit them, one or other way?

Still a bit confused about tube socket sizes. If someone could look at the listing drawings showing the socket dimensions. And advise what would be the correct knock out hole size punch to get...... would be much appreciated

Kevin I bought the Antex 660A temperature controlled analogue soldering station, about 2/3rds price of the Weller. Antex are an old long establshed UK company who make the irons in the UK. The station is made under license in China, before Covid kicked in, they visited the factory quite often. So top quality of unit is assured. I also bought a UK made solder, 26SWG 250g ROSIN FREE SOLDER, 63/37  item 263701641500
