Hank,
I didn't know any other companies sold the SRF parts besides RF Parts. Thanks
for the info on this. The way I knew about this was because of a conversation I
had with RF Parts several years back. They had the MRF454 and MRF455 remarked.
I forget now what that crossed to in their number, it's been too long.
Also, didn't another company take over the MRF line to manufacture it? I was
thinking that M/ACom did that, but ASI (Advanced Semiconductor) also gives a
replacement number now.
Best,
Will
