Any thoughts, comments, or suggestions?

Hopefully at least ONE set will be genuine! He explained how difficult is to find genuine transistors these days.

These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. They measured the hfe of the 2SCs so they send a matched pair – I see ratasheet do the same with 2SCs.

I am guessing that he may not even be aware himself that this time around there is an issues with his supplier.

But I’ve seen that over the years with other Mitsubishi devices, such as the and devices. Bipolar transistors are so named because their operation involves both electrons and holes. The only advice I can give is try the rigs manufacturer.

The customer is in the focus We want to make sure that customer is the center of attention. They did not work.

Thanks for all the suggestions. Comfort Flexible options, including door to door transportation. All 6 I received measure an HFE of 2.

In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. K2CBApr 26, Computer components Hardware Network Notebook-Battery.

I purchased 2SCs from this same broker a few years back with good results, so I did not hesitate to try him again. They may have unusually high hfe. Collector – Emitter Voltage Vceo.

The first batch I had from Eleflow worked just fine but not last lot. Especially when the power datasneet or mic 2sc192 is run low. I’ve got some ‘duff’ ones from Daatasheet just like Cliff did for a TS – mine won’t fit!!!!!

I had a long chat with him on the phone before buying them. The radio makes full power on all bands, and the power control is right on the money from w. Leads much thinner than original. The ones I have would not even fit in a TS their body being slightly bigger. Cables, Accessories Cables Accessories. Well, two separate suppliers from AliExpress, and both were counterfeit. Soldering equipment Soldering irons Soldering stations HotAir stations Desoldering stations Multifunction stations more Bias set up according to specs with no issues.

A gain of 2 sounds pretty bad to me, I would estimate a gain of around 30 might be typical on the best of devices, this could be the answer to the distortion at low power. There are tell tale signs, Writing easily smudged off, lead out thinner than usual, very shiny metal tabs that look different, the gains on the ones I have is 85 way on the high side I reckon.

However, on SSB I am hearing distortion on my transmitted signals. The fakes datashdet I got from Eleflow if I remember correctly had a gain of about 90 – and I say again they would not fit ddatasheet the TS, had all the hall marks of fakes.

G4COEApr 27, Sure would be interesting to hear their response.
