I have an older Motorola-made amplifier that uses a pair of HK-254 tubes in
push-pull, evidently an old low-band VHF jobber as it tunes up on 6m quite
nicely.
Looking in an old Radio Handbook (10th ed.) it looks that the HK-254 and
100TH are quite similiar in "typical" performance. Does anyone have any
experience with the HK-254? Was it indeed the HK "response" to the 100TH
(or maybe the other way around)? Are they similiar enough that I could use
100TH data with the -254 and expect similiar results?
Anyone have a copy of either tubes' data sheet (w/ constant current curves,
for example) they'd copy for me?
Eventually you will hear me on 6m!!!
Thanks in advance,
