cool... I should be able to get them all tightly matched then.

The majority of what I'm seeing is 315 hFE after measuring 34 devices. Is 315 good enough?

Many many thanks... I'm thinking the 2 pot board would be fine unless you all want the alps support. I shall clean up the initial post and add the boards we're considering in there

one is neg and the other pos? I'll label this as a set then correct?

here's the prices on the TKD 2500 CP 2500- 10K. @ $46 2CP 2500 10K. @ $60 3CP 2500 10K. @ $76 4CP 2500 10 K @ $94

Got it... Is an hFE of 300 good enough for this circuit?

the transistor tester measures hFE and Vf. What's are acceptable values for this circuit? How closely should I match the devices?

Funny you ask that... We can definitely add all those boards. I definitely want some of those rectifier boards myself. I was going to ask for help with the following: on the GRLV, I noticed there was an updated board. Has anyone double checked it, is it safe to produce? What is the current GRHV board? I know the tubed bal/unbal board has it's own that ranges from 100 to 250V so I'm guessing there's another. A fat one was mentioned so I wasn't sure if that was what everyone is looking for. I'll include the 100-250V board with the tubed unbal/bal board as a set if that works for everyone. Also, the circlotron power supply was requested so that would be a third PSU board. Please let me know if I'm correct on all of this

Sure, I added the TKD 4CP-601 10K to the sheet. I'll add the 2 and 4 channel versions of the CP2500 once I get a price. Does anyone want the 2 channel version of the cp601? Also, on the motorized 2 or 4 channel or both?

No minimum, but I’ll double check that Sent from my iPhone using Tapatalk

Sellmark is still active. I got an email from them this morning. The 4CP-601 10K is $50 a piece plus shipping. I asked for prices on the 2Cp and 4CP-2500 as well

Haven't received a response from Sellmark on the TKD attenuators so I contacted TKD to see what they say. Fingers crossed they'll sell direct

The one in that thread is 100-250V. Tinkerer wants the circlotron PSU, that one looks like it 500V. The ones that are mentioned above are kgsshvpssicfetsinglenewleftfatsw and kgsshvpssicfetsinglenewrightfatsw. Are those the current HV PSU boards? I just want to make sure I label the boards in the spreadsheet correctly

I haven't paid attention to the different versions lately. What version is the one posted in the tube unbal/bal board thread?

I remember Kevin posted something about pcx. They wanted a 100 piece minimum or something like that. I've got two email addresses for Sellmark. Going to try them both

I was going to contact sellmark. Last email I have from them is in 2016. Are there others? Sent from my iPhone using Tapatalk

I was reading through all that and was about to ask you... I'll use what you had before. What's the difference between the 2500 and 2511?

Spreadsheet is now open... Fill in your ID and amounts So far it's just the boards that have been mentioned above. Pay no attention to the copper and thickness for now, I'll adjust it. Feel free to post what you want here. I'll add a spot for TKD pots once I talk to the distributor. The Dynalo mini board uses 4CP-601 10K with audio taper. Does anyone want another model?

I’ll include any board you want. I just put the old spreadsheet up there so I didn’t lose it. I’ll edit it later today Sent from my iPhone using Tapatalk

noted... I wasn't going to attempt the regulators lol. Was going to use AMB regs for now.

The CFP2 is it Dynamic or electrostatic?

I'd be in for an alpha at this point

That first place had them both... Darn, guess I didn't search hard enough. I ordered 250 each of the B from arrow and a transistor tester off ebay. We'll see what kind of numbers I get.

I ordered BC546B\556B I couldn't find the C for both. Anybody see a problem with the B?
