Ham Radio Circuits and Repair / Re: TS-520 Hi Voltage Cap Question

I probably will, just trying to weight that against me fat-fingering something!  My wife reminds me often how many things that quit working after I "fixed" them... :o

I found a 120V 3.5" muffin fan that I made fit and although I can hear it running (not that big of a deal) it really moves the air!  I would be able to hear the fan and have good airflow over the finals than to run them hot.  It seems the fan is plenty happy with the reduced voltage of 100V.

That's kinda what I figgered but wanted a sanity check.  They were just delivered from Mouser about 5 minutes ago.  I am torn between saving them for "when" or replacing them proactively.  I really hate tearing into something that works fine!

Ham Radio Circuits and Repair / TS-520 Hi Voltage Cap Question

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.

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.

It was bought on-line with Receives OK bu no transmit.  I found when I got it that sometimes if I jiggled one of the switches the VFO light would go out so I took off the covers and went to town with the DeOxit and it was up and running in no time.  I think the receiver is better than my Yaesu FT-707.

I would probably still be working on it without your videos!

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.
