Hi mate been trying to get MTK952 TX & MRK980 RX on Wisy manager. All on same subnet as pc and I can ping them but they weren't showing up automatically. Turning off the master firewall settings on the pc solves it but not ideal for long term. Can you advise how I enable them through the firewall while keeping the master on to protect the pc. Cheers

Hi Andy, great to see one of these on the inside again. No surprise really that it 'just worked' with minimal attention. The TX9 was a great piece of British engineering with sometimes uncharacteristic attention to detail (like the extra support for the chopper trans in the back cover). It meant they really lasted with many soldiering on into the 21st century, probably right up to the digital switchover. You are right about there being a few 22ins versions, mostly budget sets with no remote control. I only ever saw one and remember being surprised on removing the back cover to find a TX9 lurking inside! All the very best, Ian E

Hey Andy, Nice to see one of these TX9s again. Little beauty of a set and generally very reliable. On the MK1 ( I can't remember the board number) I recall that one of the causes of fuses shattering intermittently was a zener diode (135v, I think) that would trigger a SCR into shorting across the smoothing cap. It was a fine example of a crowbar circuit! What could happen was that the zener diode would become a little bit too noisy (zeners can be used as white noise generators). If the noise was above a certain level it would fire the SCR, and bang went the fuse! Dry joints under that red cover were common. If a pin was too badly oxidised, I'd remove it and file down to clean copper before resoldering. The degaussing dual posistor would also usually get dry joints because the pins were so thin. Again, removing and filing the pins to clean metal would usually solve it.... So long as the posistor buttons had not cracked or perished! Keep up the good work..... It's great to watch and relive those memories. All the best!!
