RF AMP MOD FOR THE SB-101

[Allan D. Fritsche]

Hello Gang, In an effort to increase the receiver sensitivity on my finally
restored SB-101.. I recall that there was a certain mode to change out the
6AU6 rf amp tube with a 6HS6. Iam pretty sure this was in a QST in the late
70's, but my collection of QST's stop at 1973 and go down... Well I bought
a NOS 6HS6 and just plugged it in, didn't appear to change things much..
Perhaps certain pins need to be rewired?

Any help appreciated..
