Appreciate the tips and attention to the subject matter. Counterfeits are definitely an issue.

[@ellensburgamplifier]

Thank you. I enjoy exposing this and keeping people up to date on the issue.

[@Tekjive]

This is why I only buy from certain vendors, the one time I tried to score a deal for a client who was hurting with the quote it backfired, and I am now covering that loss, cuz in the end I pulled the trigger. Good video

[@ellensburgamplifier]

A good vendor will be able to provide you X-ray evaluations of their transistors.

[@ricksampson6780]

Most interesting information, R&D departments should be across this issue, cheers.

[@ellensburgamplifier]

Thank you for the channel support. They are getting a little better at making them look authentic. I recently had a 5k amplifier in that another tech could not get running. When it came in I instantly recognized the fake output transistors he installed.

[@ricksampson6780]

@@ellensburgamplifierThe onus is on the manufacturer to destroy components immediately after they have failed the QA process.

[@ellensburgamplifier]

@@ricksampson6780 I think this is where we see all the re-pined transistors come from? I would think the manufacture would put it through a shredder.

[@Satchmoeddie]

A good old LCR and a good old Tektronix curve tracer will reveal the truth. RF finals are one of the worst to get stung on at $100-$1,000 each. Lots of what I buy is obsolete and NLA from most legit suppliers.

[@brianwaynehughes]

Fantastic content as always Todd! Thanks for this!

[@ellensburgamplifier]

Thank you Brian for the support!

[@roybrown4944]

Why aren't the reputable companies selling on the regular sites

[@ellensburgamplifier]

I guess it depends on what you mean by regular sites. Reputable distributors don't list their parts outside of their websites (thank goodness!)

[@grahamhall2662]

It's a big issue. So easy for rogue manufacture's to deceive and many do. You could have included a few simple electrical tests to point novice like me in the right direction. On resistance is easy for example.

[@generalingwer4341]

Unless it was pulled from a unit:their all fakes.if part is not in current production,its gonna be fake.

[@bobert4522]

Companies xray them now to compare against the known real model. Was a big and continuing issue during covid when companies were third party bidding on lots of parts. Pays to know your source!

[@cartycartyamplifiersalesrepair]

OH yah great great video thanks you for explaining 👍 👍 🙏 🙏

[@Tallamango2024Pallamango]

That's why i don't repair if transistors are blown. I buy new one.

[@danielchatrie3517]

Utsource’s sell only original parts

[@G.M.C_Electronics]

Hi..can you put romanian translate also?thx

[@ellensburgamplifier]

Thank you for the feedback and I will see how to do that.

[@FrozenPaint]

You wouldn't happen to have a source for two IRFB31N20D would you? They've been EOL'd. I couldn't justify the $40 (after shipping) Arrow wanted for their last 2 FETs and they sold out before I had time to finish compiling a proper order.

[@ellensburgamplifier]

I hunted high and low in 2019 for a good source. the 31N20D is a tricky one. I think I have a video on how to properly identify one. Unfortunately, I do not know of a good source now. I bought out what I could find back then.

[@FrozenPaint]

@@ellensburgamplifier Shame. I suppose I'll either have to scrap it or try my luck finding a sub. Thanks for the reply!

[@danielchatrie3517]

The cost of original parts cost 3 time I buy mosfet for 5 dollars per one and 12 dollars for igbt

[@awaazhoosein6565]

Where can i buy genuine parts

[@ellensburgamplifier]

Mouser, Digikey, LCSC, Newark, and Arrow are a few places to get parts from.

[@Islandboyzadventure]

​@@ellensburgamplifierhow's utsource?

[@ellensburgamplifier]

@@Islandboyzadventure I received the wrong parts (with the other customers invoice) and they did nothing to rectify the problem also I have received counterfeit parts from them so I will never purchase from them again.

[@Islandboyzadventure]

Ok out of the list you post which have the best stock and shipping ?
