Great! When the RIP MY T2 was announced, I said to myself - James will have a new T2 ready in 10 to 14 days… Now only three days has elapsed. No rush, James.

Have used the 300B tubes with DIY T2 for three months now. First two months with an amplifier with all original transistors and the last month with an all-modern transistors’ amplifier. Only issue so far is a failed small solid-state relay in filament supply. Otherwise, I find the DIY T2/300B pleasant.

A wise person once told me - the only sure thing is that it is uncertain (google translated from Swedish).

My torque setting of 82 Ncm equals to 0.82 Nm, or? Upper post’s 8-9 Nm must equal to 800-900 Ncm This link is very handy. https://www.convertunits.com/from/N-cm/to/N-m 😉

Used above setting for a long time and haven't had any issues so far – knock on wood. Also, in JoaMat kitchen we don’t use any kind of thermal compound... , but we use

I believe the space around the rectifiers makes it risk free to use the uninsulated version on the original Kevin T2 PSU board.

New T2 - great @s_r Remote diagnosis is not easy… but the dark LED in red circle – is it dead or wrong orientation? Diode test might give some answer.

They do sell as spare parts. You just have to dig deep enough. Click this link and scroll down till you find side panels 1/2/3/4 U and lengths of 170/230/280/350 mm. -
Seems you have built yourself a good amplifier – Congratulations! To get rid of those annoying offsets – build KGOOS.

Interesting item. I use Pomona model 6341. On my third pair now – after some use it seems that the wire break at the handle edge - else I like them. Probe Master looks good so I ordered a pair. Can be bought in EU at https://eleshop.eu/probe-master-8150-spring-loaded-micro-tip-test-lead-kit.html and/or https://www.welectron.com/Probe-Master-8150-Spring-Loaded-Micro-Tip-Test-Lead-Kit_1 . -

Yes, Kevin’s design. Just added one 6922 and two resistors. I have a lot of 6922 doing nothing. -

Inspired by Satyrnine's project and an attempt to recover from my Tube input CFA3smd failure some time ago I’ve been busy with this today. I call it Cascode Tube Input Something - intended for my CFA3smd something. +220/+15/-15V and filament needed. Based on ubaltoblatubeschem2, thank you Kevin.
