Re: {Collins} 30L-1 grid resistors & Archive Searching



George -

The Ohmite resistors are ceramic composition, Type OX and OY for 1 and 2W versions.  Mouser stocks them.

I just recently heard that Mouser also now stocks newly manufactured carbon composition resistors! I have not researched them yet.

I think it is Ohmite that has a metal oxide resistor that is specifically
advertised as a carbon comp replacement and as being non-inductive. The
Budster, K7RMT, used them and I have some in the shop but do not remember
the part number. They work really well.

Does anyone else have that part number?

This thread has shown up before, and I would suggest searching the archives,
but they are still not working.

By the way, we have checked on the archives, and there was a problem (They
were going to make them listserve "private" where you had to log on to
listserve to use them - BUT we balked at that). They are now making the
archive searching public for us, but that required rebuilding the search
listing on another portion of the server bank, so it is taking more time.
They are coming they say within a week.

Subject: {Collins} 30L-1 grid resistors

I am going to replace the resistors in the grids of the tubes of my 30L-1.
The parts list says 1 watt, 47 ohm, composition.  Several have recommended
going to 2 watt resistors.  Composition resistors seem to be a thing of the
past.    Are "metal oxide" resistors OK to use?

Thanks,
George
