No response. Ordered a couple from Qservice.

It depends very much on the specific fan brand/model/design. I have often added R/C networks to drop fan speed and noise. Some fans work just fine, while others don't. When you drop enough voltage to

That should be easy enough - use 47uF 35V dry Ta caps, and you won't have to worry about what the actual supply voltages are in each spot. Ed

I wanted to do the same thing to limit the power output of a transformer. The problem is for all the useful power limiting values of capacitance, transformer inductance resonates with it near the

The capacitors in question are 50 uF, 25 V. I also found that the elapsed time meter had corroded so I pulled it out.

The 109Ds are wet-slug Ta caps. If they are just used for supply bypassing, you can replace them with similar-sized dry type solid Ta caps. But, watch the voltage rating versus the supply voltages -

Even though it was working properly at the time, back in 2011 I preemptively replaced all of the surface mounted electrolytic capacitors in my 1992 vintage 492BP. In doing so I found a few that had

I gave in and ordered the fan ...

No can do :(

Hi David, Stupid question ...I'm assuming this is not a tapped transformer input so you just leave the fan across 1/2 the primary? Other than that I would go for the replacement fan, from the little

Random thought, use the 120V mains winding on the transformer as an auto transformer just for the fan ? Robin Sent from my iPhone

Converting a 120V unit (it's OK with 50Hz) to 240V. Problem is that the fan is a 115V unit (p/n 1123XBT). I initially thought of a resistor in series, but I'm thinking that would dissipate a LOT of

Morning Dave: I tried to find that earlier exchange (I thought had seen) but could not. While this interface is a BIG improvement on yahoo the photo search is surprising in it's absence. Photos are

Moderator, Not sure if it's already stated, but it would be good idea to state in the photo upload rules to always name your album folder starting with the device model number. Rick

Update. I'm up at the farm and have been digging through fittings and parts - finding things that haven't seen the light of day for years - but still can't find my "official" jars of compression

Interesting box. It appears that Metrotek was involved in non-destructive ultrasonic testing. Also note that they were in Richland, WA, home of the (in)famous Hanford Works. Metrotek was bought and

I'd have to go out the shed and check the original can. It is pitch dark and near freezing - so not just at the moment!

Did you get hold of the actual specification they determined? --Toby

The moderator acknowledged that the photo search function was broken and he was in contact with groups IO to see if it could be fixed. I think you will find they are in alphabetical order which helps

Is there any possibility of a search function for Photos?
