44-hp-8590a-spectrum-analyzer-repair
In the previous video I replaced a par of blown diodes in the RF mixer of HP 8590A with Avago (Broadcom) HSMS-2802. In this video I experimented with HSMS-2812, HSMS-2822 and even with unmatched pair of 1N5711.

128-high-end-pioneer-elite-sc-09tx
This hi-end beast stopped turning on. It is very complex and weighs a ton. It was quite tricky to investigate the fault.

A sheet of paper was added between the spacer and the overlay film, a few more things were tried as well. It seems that a thicker spacer should help, but I don't have the means to make one at the moment.

142-shure-psm300-transmitter-repair
This Shure PSM300 P3T transmitter did not show any audio level on the display, and the receiver did not show the blue light (but showed the RF level). The fault was traced to a tiny (0402) 1 ohm resistor on the output from the 9V regulator, so that the audio section did not get power.

Someone tossed out this Toshiba HD TV. It turned out to have a faulty LED driver chip, which was replaced. It seems that thermal management of this chip was not designed very well.

48-datron-1071-display-replacement-part
The meter I repaired in my previous video still has a bad gas discharge display. In this video a project to build a replacement was started. Three different approaches were discussed and prototypes built using Atmel Mega 328p micro-controller. The software was written in C and assembly languages in Arduino environment.
