Q: (18390)

I own vacuum tube home audio preamplifiers. The amplifier in particular runs pretty hot due to 8 KT120 power tubes, as do the smaller 12au7 signal tubes. The preamp gets warm with the 2 5ar4 rectifier tubes & 12au7 signal tubes. Total of 22 tubes combined. I purchased your vacuum tube survival kit (SK-GXMD).

I am wondering if the DeoxIT® Gold GXMD 100% solution that came with it can also be used on my male and female RCA connections on both my gear and interconnects, also my banana connectors on my speaker cables binding posts? I know the Gold GXMD is for higher temp applications, but will it work for my other connections? I think the VTSK is fantastic! If my contacts connections are clean, do I really need to use the DeoxIT D25L? I use it mainly on my tube pins, which is where most if not all the oxidization & crud occurs.

Just a follow up. If you do not have one of our Vacuum Tube Kits and want to try using our standard DeoxIT® products (DeoxIT® D-Series or DeoxIT® Gold G-Series), apply to pins and check after a few hours/days of use. If tubes/pins get very hot, we would recommend using the GxMD Kit.

NOTE: Don't use a spray to treat tubes/pins/sockets. Use our brush bottles (D100L-2DB, G100l-2DB). If you only have a spray, spray onto a lint-free foam swab and dabbed the vacuum tube pins, then insert into socked.

Regards,
Dr. DeoxIT®

A:

Yes, the DeoxIT® Gold GxMD can be used on other contacts. However, it does not have any cleaning or deoxidizing capabilities. So, if there is any oxidation on contacts/connectors that you want to use on, I would use the DeoxIT® D25L first.  Just apply and leave on for a few minutes, to overnight if oxidation is severe, then wipe off and apply the DeoxIT® Gold GxMD. If surfaces look very clean, just apply the D25L, then leave on for 5 minutes, wipe and apply the DeoxIT® Gold GxMD.
