Re: TeddyReg

Isn't it just the way. I look for ages and then post this and upon returning to google find 2n5484 in the Belleson cct which is almost identical and it's available. Oh well, maybe good info. EDIT: However, upon simulation the performance is nowhere near as good as the 2SK369. EDIT2: After trying a b...

The jfets were 2sk363bl (shown as 2sk369) but are now unobtanium.

Does anyone have a suggestion as to what I could use to drive the D44H11 and as the current source?

Re: Is this a Valve of some kind?

Re: uController for Amp

I'm not a valve roller mostly. Sure there's differences but there's more to be had in topology IMHO. My aim with this was to try and avoid a costly failure and also to give me an idea as to when to try a spare set to see if the working set were past their best before date. My use is virtually the sa...

Re: uController for Amp

I like the ideas that get suggested on these threads even when they get a bit more extreme. Might not be needed this time but for another project who knows. I suppose my loss of power thoughts were based on our last house which had an overly sensitive RCD and was a bit trippy. That combined with the...

I have just read this before I go to bed a bit drunk and it's given me a good giggle.

Re: uController for Amp

So far this is going well in The Matrix. Was wondering if it's feasible to hold up the Arduino long enough with a supercapacitor to write the hourmeter to EEPROM in case of a random turn off. Normally it would be a managed turn off which would trigger the turnoff function but in case of power failur...

Re: uController for Amp

As I haven't got any hardware yet, thought I'd look into simulation and found TinkerCad. It's very basic but has got me started doing some basic stuff. Got the cathode current display bit going which wasn't too taxing. Assembled some sig gens to generate a "music" signal sort of thing to s...

Re: Millard working week

Standout for me has been when women in Switzerland got the vote. 1971! Numbers and statisitcs are the weapons abused in political spaces. Vacancies very high. Government claims super low unemployment yet to be employed, requires only 1 hour of work in the week and that doesn't necessarily require pa...

Re: uController for Amp

Thanks and I appreciate the offer. If I was still down the road in Kent, I'd be up for it but in NZ now and I looked up the postage; not far off a new book price here :shock:
