Hello gents, interest whet by this topic I've just found my "stock" of rod pentodes and they are 1j29b's, are they useful at low anode voltage's like the 1j24b's? I've tinkered a couple of nice syncrodyne/re-gen hybrid radios using a Franklin oscillator topology with a JAN6418 as an input device and an 18volt ht, these are very good, but are photo sensitive (not a problem) and very microphonic (problem!) Would the rod pentodes be an improvement I'm wondering?
Cheers, Andy.
