I've purchased from MPJA numerous times and never had an issue. As to the catalog photos, I just think they're lazy and not doing the photos, but are pulling them from a stock photo somewhere.

There? is a huge flag that the items shown are not even in a real photo. When you click on the RH image what comes up is a 3d impression with non real codes on it. So what the hell - do they even have them to photograph. I hate it when semi conductor vendors do this. If it is an Ebay seller? I don't want to know as likely he is selling product he does not have in stock? but he can get at the local bazaar .? That is forbidden in Ebay vendor policy, he can be struck off Ebay for doing that if you report it.
IRFz24 is a nice RF subs for the IRF510.? It has been used to produce 45 W PEP in 7 Mhz ccts? in ARRL supervised tests.? ?They are around 80c each from Tier one suppliers. Also they will come out of the same tube in general so are likely to be closer matched. Thermally they are about 30 percent better. Don' t go past the STP60N Mosfet either as used in the Texas topper RF amp. it has Cin intermediate between the IRF510 an the? z24 as mentioned above.? What world of possibilities to choose from !!!
