Years after years, everyone is collecting things that "can be usefull"... But, at a certain time, a housework is necessary !
I have to get rid of a lot of parts and equipments. I have created a small online shop on my Joomla site, using the Virtuemart component.
I didn't setup a online shipping and payment system, so if you need something, please feel free to contact me !
The link to the shop is in the menu under "eShop".
A friend of mine who bought a cheap Kenwood TL922 power amplifier asked me to repair it and to bring some modifications in order to improve the security. This is the fruit of my works...
So, before any tests i have made the following modifications :
- Step-start
- Filament transformer protection
- HV protection agiainst internal valve flash
- Zener diode substitution
- PTT circuit modification ofr low voltage switching
- RF relay substitution
- RF stability improvement
- Symetrical tube feeding
Since the beginning, my brand new TS590s had a intermittent problem. The reception was fading and sometimes disappeared completely. Sometimes, the TX went away and at the same time, the HI/SHIFT setting didn't work above 3000 Hz.
I noticed that a slight shock on the case brought the rig back to live, but not always. Being new and under warranty, i sent the rig back for repair.
