Holco H2-H4-H8

I have several thousand of these old non magnetic Holco resistors.

I originally bought them because I wanted some specific values.

I’m just testing the audience. Is there an interest in me listing those surplus to me? The price will be $1/pcs, min 50 assorted or one type, plain non-registered envelope. $5 in fixed shipping cost.

Of course if someone wants a substantial amount, reduced price and registered shipping will be made available.

Thanks for looking.

Hello guys,

The last year I bought some matched mosfets from RM.
I paid extra for the matching!
When I got the package I just measured the mosfets with the dmm. Everything was good so I stashed them together with my other precious semis. These were to be used in a blowtorch clone.
This year the time to build the blowtorch had come and this time I connected the mosfets from RM to a temperature controlled rig to check how good they were matched.
To my surprise the mosfets were not matched.
So I contacted RM and explained about my problem, even if one year passed already he agreed to send some replacements matched exactly like I asked the first time.
I had paid with paypal friends and family and one year passed by already so if he wanted to play dirty he could do it.
After a long wait(I thought he wouldn’t send anything) I received my matched octet of mosfets and an extra octet. These were tightly matched so nothing to complain about this time.

RM is a good guy but very slow, so maybe you need to have a bit more patience?

PS. It happened the same to me that he accessed the forum and didn’t reply to my messages but in the end he solved it like a gentleman, who knows maybe the man is in a vacation(like he mentioned earlier)or maybe he has some serious problems…
So wait a bit more… this if your house doesn’t burn out because of this.

Patience? He was responding fairly quickly with private messaging until he just stopped one day. Nothing but silence from him. I've asked for a PayPal refund from him which has been ignored. He was on this site yesterday and yet he cannot give me my money back?

I am a retiree on a limited income (with serious health issues) just trying to have a little enjoyment out of tinkering with audio and my money is taken? It is totally on me to have used PayPal F&F and I have no recourse to get money back. His account here should be suspended.
Hi guys, the last 2-3 three weeks I have been to and fro. I ended up with buying a house in Sweden, where my kids live. The transaction is now concluded and I`m back in business.

Sorry for the delay, the distance between my current location and the new one, is about 600km, one way. I have traveled there five times in the last three weeks so I haven`t been able to communicate.

All outstanding orders will go out today.
