Great to hear that you are OK Andy

Glad to know your ok!

Hope you start feeling better friend

A million apologies guys – it’s been so long since I was on FISD that Paul Troopermaster drove to my house last night to make sure I was ok!   

 

Thanks very much for making that effort Paul, and thanks to all the guys who’ve emailed/PMed well-wishing messages.  I feel I should explain a bit about why I’ve been so hard to get hold of.

 

I have a long-term health condition which has been worse this year and has been really bad the last few months.  It isn’t life-threatening but it impacts heavily on my life and what I’m able to do.  I usually manage it quite well but this year’s been much tougher and eventually I became totally exhausted.  I had to just stop everything, not just FISD

 

I feel really bad how long some people are waiting for things they asked me to make (and in some cases I’ve not even managed to reply to messages ).  All I can do is apologise and assure you that it’s not intentional & I’ll remedy it as soon as I can.

 

I promise I haven’t forgotten about any of you.  I do still hope to make all the blaster parts that are on the waiting lists and start making the E11 stands (although that’s clearly going to be a 2016 project now…)  In fact, I’ve got 2 sets of Power Cylinders that got nearly finished and I’m going to try to finish them before Christmas… 

 

If you’ve contacted me about anything and I didn’t reply, please accept my apologies and try again.  (I have 6 email accounts with a billion unanswered emails – I’ll try to work through them but a fresh email is more likely to get noticed & replied to.)

 

Cheers, Andy

Good to have you back Andy and hope your illness is relatively under control, Long term heath condition are a terrible affliction and your life can change dramatically, I know from experience having being diagnosed with a bowel disease several years ago, I was sick for most of this year and only now have things under control with medication and diet etc.

The force is strong with you and also we all have The force Awakens to look forward too soon!

Take it easy pal.

regards

Chris

Glad to see your ok and yes you must look after number 1 first.

FISD is here for you when your ready.

Glad to hear an update Andy. I'm sorry to hear your health has been hijacking your life. That's never fun. Hopefully your health starts to improve in 2016. <br><br>

I'm still on your list for a kit this winter, but I'm in no rush. Take care of yourself first. We will always be here.

[veektohr]

Glad to hear you're on the mend! I just read through this entire thread in one go, and I'm unbelievably impressed. Your work is amazing!

[PlayfulWolfCub]

Thanks for all the kind words, guys - It means a lot     (I hadn't realised it'd been 2 months since I'd even signed into FISD!    )

 

I've just posted a bunch of updates in sales threads if anyone's waiting on orders & I'm aiming to reply to all personal messages this week.

 

Cheers, Andy

This isn't a lead or anything, but I was upgrading/doing maintenance on this early 70s receiver and it reminded me of this. Just thought it would be fun to share since I don't see things in a line like that very often. Not the same obv, but I was excited when I saw in nonetheless.

[Herwig]

Could anyone please give me a hint, why the center capacitors solderd with the red end to the metal of the frame? As an electrician I would believe that the black end (cathode) is connected with the ground of the case.

[themaninthesuitcase[Admin]]

I would have to assume a chassis ground. I don't know what image you're looking at for the red/black ends but another thing to consider is in the early days of transistors positive earth was common due to the prevalence of PNP transistors.

[Herwig]

Thank you very much! On the most pictures of new builded power cylinder I found, the "Metalmite" capacitors are solderd together on the chassis with the side of the red cap. The pictures from Michael Washko from the "Power Cylinders Resource", showing the capaitors unpainted, made me think about it.

 

But your argument is absolutly plausible!

[themaninthesuitcase[Admin]]

The Metalmite capacitors, are to my knowledge, not polarised as they lack any form of polar markings. From a quick google they are paper capacitors, which probably means "paper in oil" which is a primitive capacitor technology. Polarised Electrolytic capacitors would have been physically bigger and also have a much higher capacitance.

 

Looking around, not all of them have red and black ends, some have two black.

 

For example:
https://www.ebay.co.uk/itm/305583460268?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338590836&toolid=10044&customid=95cbffdf7f7c1f563ab398ca56115666

 

 

Admittedly not quite the correct one, these are 1000v caps which will be larger, but finding images of the correct smaller ones vs repo is hard now.

 

Those that do have 2 colours might be an indicator of which is the "foil" which can help reduce noise in some circuits.

 

This is all a bit of a guess though, as finding the actual data sheet on these is impossible now.
