Ham Radio Circuits and Repair / TS-520 Hi Voltage Cap Question
« on: November 19, 2019, 01:34:13 AM »
I am wondering if the Nichicon 150uf 600V units would be a good replacement for the stock 100uf 500V parts.  I've always been kind of a "more is better" person when it comes to electrolytic caps.

Ham Radio Circuits and Repair / Wimpy TS-520 Cooling Fan
« on: November 18, 2019, 10:01:53 PM »
I just got a new (to me) TS-520 on Saturday and after watching some of Buddy's videos I got it up and running.  But, is it just me or is the cooling fan about the wimpiest fan on record?  When I first got it I could watch the blades turn and after disassembling it and lubing the bearings (bushings) with Mobil 1 motor oil it runs faster but there is still virtually no airflow.  I have bought a 3.5" 120VAC muffin fan off fleabay and I hope this will run off of the 100VAC running to the stock fan.  Kind of an odd voltage to be sending to a fan IMHO.  If it doesn't run correctly I'll find a switched 120V source in the radio to send over to it.

Is this a common issue or am I over reacting?  I made a few contacts on Sunday and was told it sounded very good but as the day wore on the meter was acting screwy when I tried to touch up the tuning after changing bands.  That's when I noticed the fan poking along and I have not tried operating again after oiling the fan.

I would like to thank the admin for the great Ts-520 videos.  After watching them I was able to get my "new" 520SE working this morning about an hour after FedEx left it on the porch!

I originally had a Novice ticket in the late 60s and never was able to get code speed over 10 WPM so it lapsed.  Fast forward to 2019 and I passed my General test a couple months ago so I am trying to pick back up where I left off.
