EICO 369 Purchase

[Chris K]

After buying 2 electromechanical Knight sweep generators I could not get working, I bought an EICO 369 on eBay for alignments on older TVs using frequencies in the 25 Mhz range. Has anyone used one of these? I have the manual that has around 5 pages of service bulletins suggesting significant changes in capacitor and resistor values, lead length etc... Has anyone done these changes and did it significantly improve performance?
