Quadrovibe

I don't think that is possible with a switch. One possible mod is to leave off the switch and T1 entirely and use a 10k pot wired as a variable resistor for R5. This would let you blend between the two modes, more or less.

I have not tried this....just occurred to me. There might be some crackling with that blend pot, though.

I do have a very small number of the lamps on-hand, and I will be including them on international orders at no charge since they may be hard to get overseas. Note that you can use the 7371 lamp in place of the one I used...it's just a bit taller than the JKL which might make it hard to put the Quadrovibe in a 1590B.

Wow thanks a lot Sir ! I order immediately
