1949? Motorola 10VT24R, TS-14B chassis
Hey ya'll, It's been a little while. Well I thought I was going to be getting to my Zenith SC, but the space I had reserved for pulling it apart in is not available anymore at the moment, and like I said before, I'm not dragging it down to the basement. For now, It'll wait.
![]() Anyway's, after recapping some radio's, I've decided to get into this set. It's allready got an issue. Well, what's new about that. ![]() So far, I've replaced all the Electrolytic caps, some paper that looked suspicious, and some that were clustered together around the suspicious one's since I was on a role... I have more to go. I also allready swapped the celenium's for 1N4007 diode's. Unfortunatly I dont have a schematic to go by for this one. It's on ETF's site but it's too hard to read...http://www.earlytelevision.org/pdf/m...4_manual.pdfSo i've been going with what's in the set since it was complete and didn't look burnt. Well, I tried a power up and... blew an E-cap ![]() It was only at 30V!...I also found that none of the tubes had lit up(all are good) and I had really heated up another e-cap. Both of these caps are connected to the diode's. The diodes are wired in the same as the celeniums were. positive-negative wise. I never added any resistors too them. (I don't know if they need them or not.) The cap that blew was a replacement for 140mfd/150v. I had 147mf/160v in place and it heated the 100mfd/300v cap up. Nothing that I could see was shorted out on another component, so why would it do this with only 30v being introduced into the set??? some pics. Note: I know my e-caps look like a mess, but nothing is touching what it shouldn't be. I also have pictures of what I beleive is a capacitor. Is that the value on the backside or a part# that looks like a cap value? I havn't come across capacitors that look like that one yet. |
