MGS is pleased to announce that we will be offering a LARGE selection of hard to find RF and microwave related items! After many customer requests to expand the very popular “President’s page” section, we have decided to expand the MGS product line to include military and commercial surplus RF and microwave items at VERY affordable prices, and with our famous MGS customer service and satisfaction guarantee. We will also be able to take many payment forms such as Visa and Mastercard, which are not available on the President’s page. Adding these lines to our website will take some time, but watch this section for an ever expanding list of vacuum variable capacitors, vacuum relays, tube sockets, high-end microwave components, and much, much more! If you have these items to sell, email us your list! (Photos helpful)
