Hi, I am looking for a replacement Capacitor for my Kriesler 11-28 radio.
I need two, .05 μF x 400 VDC capacitors.
I have been able to source all the others in the radio.
Is there anywhere in Australia I can get the .05 (.047) . I note that an increase in voltage is OK.
Barry

Evatco in Queensland have a range of capacitors and other components.

Try this link http://evatco.com.au/.

Hi Barry,

If you have a Jaycar nearby they keep a small range of greencaps that are 630 volt. Cat # RG-5204 and RG-5205 are both 0.047μF. Evatco has them as well as other online stores. The Services Directory link above has some links.

Cheers,

Warren

Only one pair? If this still has wax paper caps in it and tired old electrolytics, one replaces the lot. 630V is now the voltage of the common HV valve radio caps.

I would note that EVATCO also has a range of higher wattage resistors as often used in mass screen & B+ voltage dropping & some cathodes.

Facettor did say : "I have been able to source all the others in the radio", so I figure he intends to replace all capacitors.

I prefer to try & source the caps all of the same type; It looks better. The axial's are better for replacing wax paper axial's, but .....

In some cases a ceramic or the "greencap" can be mounted neatly on the socket, but leave a little bit of distance for heat. That also applies to mainly cathode bypass electrolytics, where you can mount higher temp RB type on the socket, as the modern caps are much smaller (heat rises) keep them low, not high in the pan and close to the side if possible.

RS Components may have Red Green cap (did not look) I think I got my last lot of SM's there, as they had the range I needed.

^ I've taken note of that fellow's eBay name.

I think the services section on here could be freshened up to list such recommendations. Fine line between that and advertising I know but, heck, there are precious few such suppliers left these so why not give them a plug to help them stay in business to help us in return?

I think the most difficult thing about the Services Directory is that nothing seems to stay relevant for long. At one stage I gave some serious thought to scrapping the current setup and handing submissions over to the people offering the services as this is how most web directories (including two big ones I used to own and run) work. The problem with this is that we'd have the same situation with stale entries, going by previous experiences.

On the other hand, I could easily write a script to manage the submissions, search and display of submissions and just see how things go. The ironic thing is that the directory script I authored back in 2002 is an early cut-down version of the Hansard software that powers this site. The site's layout is even similar and was developed at a time I needed a content management system that could operate as a weblog, a set of forums or a web directory script. Depending on the site I was preparing for launch I would upload the basic template and just 'bolt on' the needed pages and the correct database. At the peak of operation I had something like a dozen sites running and to be honest I don't know how I managed it because I certainly couldn't now, though during that time I managed to learn a bit about how to control spammers and automated signups which was important then as it is now.

This site is the sole survivor from that era. That's no accident - as the other sites either lost relevance or could no longer be managed in the best way possible. Neither of those scenarios are likely here. Smile

I'd be interested to get an idea from members as to what they think should become of the Services Directory. The content not only needs updating but the concept perhaps needs a bit of a re-jig too.

Discussion points could include:-

1. Continue it as a static page and update information manually.
2. Introduce a submission engine and promote a member here to manage the approval of submissions according to a set of guidelines (assuming someone wants to put their hand up to volunteer for this).
3. Introduce a submission engine and simply permit anyone with membership status to submit an entry and have it go live immediately, again according to a set of guidelines.

Good topic. I think it should have its own thread.
