[R-390] Role of the 3TF7 in PTO frequency changes

[Craig C. Heaton]

So, you would leave failed components in a radio? Inquiring minds would like
to know? Long live BBOD's!

Now a comment to the replacement of original parts with new ones. I
would e.g. NEVER replace original capacitors with orange drops. In my
eyes they are oversized and look unaesthetically (the orange drop
lovers will kill me). If possible I'd avoid any soldering in the
radio. That was the 'ultima ratio' when designing the 3TF7
replacement. But if a replacement (even a solid state device, Hallo
Heinz Breuer) fits well into the look of the radio I see no problem to
install it. The 3TF7 replacement with the medium size IERC tube shield
installed (http://schmid-mainz.de/Flyer.pdf) to my feeling isn't
recognized as a foreign body even by the purist.
