Ramblings - heads up for spring Expo - April 27-29.Winter Clearance ongoing - you'll still find great deals.I have gotten very lucky with a few batches of obvious "clone or fake" transistors ad far as being within spec and functionality, and I knew from the price, packaging, labeling they were 99% cloned but the plastic Palomar's are a bit worrisome ! Just hoping to find a decent amp for $.50 a watt built in the USA and I will swap out any cheap components myself lol !! Just hope they are not complete Chinese imports with faceplates As soon as I hear from Rocketbox hopefully I will have pics and data sheets ! I want to see the HD-500 with the hood open, if its an Alibaba.Midwest Mountaineering: Coupons and Eventsįree Stainless Mug with purchase on February 29th - Leap Year Day onlyĬlick on the coupon for a printable version. I have never seen or heard of his Palomar Transistors or been able to find any info but hopefully they are not being used in the boxes lol. Waiting to hear back from Rocketbox directly and asked for pics and data sheets for the current HD-500 and the upcoming XL1000. I saw on one Facebook post to allow 3-5 days for build time (not exact quote) so I believe they are at least assembled in the USA. I contacted an eBay seller as well as leaving a Facebook message and the builder is (from what I'm told ) currently on vacation but lives here in the USA in Las Vegas. Hopimg for the best and invited them to join Worlwide DX and spread the word !!

If you understand this ahead of time and don't choose a model that will have to be pushed in order to reach your goal, you'll probably be happy with the cost and performance. They run hotter than the old bipolar transistors too. That bias also increases the operating gain of a part that struggles to maintain stability due to high inductance and the larger RF currents related to a lower operating voltage producing hundreds of watts. They include adding everything from extra resistors shunting the bias voltage across the gates to using transistors with much higher peak current ratings, hoping that will translate into some ability to sustain AB bias without failure. Because of that, the ones that are working are almost certainly relabeled switch mode transistors not intended to support bias or linear operation.Īll types of tricks are being used to make them function in the linear mode at the expense of reliability and durability. People considering a 12 volt MOSFET amplifier should beware that not a single reputable transistor manufacturer is advertising a 12 volt linear RF MOSFET datasheet in this type of plastic package at power levels this high.
