Recently I acquired an Eico HFT 92 AM/FM radio made back in 1958. The unit has had some decent modifications done such as replacing the rectifier tube with silicon diodes and replacing the main filter capacitor with electrolytic capacitors. When I powered it up FM wouldn't tune past 105Mhz. I checked the FM tuner front end assembly and found a capacitor not soldered to the coil from the Plate B+ to and ground on the other side of the coil. Some calibration was needed on the trimmer capacitor on the tuner. My question is AM is extremely weak. When I tap on the tube I get all kinds of snapping and... -
This ultra compact PC wont power on.
It has been replaced with a more modern cyber-secure PC (i.e. one that supports Windows 11 as this is a 4th Gen i5) so although technically it's not worth repairing, I would like to use this as a training opportunity to see if (with your help) I/we can fix it as that way I can learn something from a computer with a genuine fault...
=========================================
On plugging it in to my bench power supply it starts to draw around 160mA whereas from the other Ultra Compact PCs I've successfully fixed it should...11-10-2025, 04:30 AM -
Hi:
i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.
I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?
If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

Hello,
I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.
Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,...
