Do you have a multi-meter to confirm the capacitance? If the lead is totally torn off when you may have to test the other crossover. One leg of the cap will have to be lifted from the board too. Assuming it's a 5.6uf film cap, then there's hundreds of choices; Solen Fastcap is an affordable choice f...

5.6uF make sense. I don't think it's an electrolytic cap, so it's probably not necessary to change it.

Digikey carries Nichicon DB series caps which are made for speaker crossovers. I had a quick look and I think they have everything you need. The DB series will be a simple replacement as they are radial style leads (two on the bottom vs each end of the cap). Here's the datasheet from Nichicon: http:...

Measuring old caps for capacitance only really tells part of the story, you need to measure for ESR as well. Better yet just change them since it's cheap and easy, and even if the old caps still test OK, they are guaranteed to fail someday. Tom_r, you are absolutely right, lots of guys think old vin...

There has never been any schematics or service manuals released for Sunfire amplifiers. Bill Flannery is the only guy doing repairs who is endorsed by Bob Carver, he was one of the service Techs at the old Sunfire Corp:

The tubes such as EH which offer both gold and standard pins have an added complication to consider: the gold is added on top of the standard pins, increasing the diameter slightly. The larger pin may make better contact with the tube socket, but it will also potentially stretch the metal receptacle...

This is sad news. I dealt with Classe's service department on a couple of occasions, and they were great to deal with.

There is nothing inherently desirable about the 7DJ8, the only reason you see them being sold is because the proper 6DJ8 tubes are getting rare and expensive in certain old stock brands. The correct tube for that preamp is the 6DJ8 / 6922 / 7308 or russian 6H23. Your can't slap in any old 6DJ8 / 692...

I started using the credit card option when paying for ebay purchases thinking that my credit card would do the currency conversion but I think paypal is still doing it. I have the Rogers card and it clearly identified foreign transactions from my trip to Europe this summer. My ebay purchases are s...

I think I found a work around this issue and you can set the default to always go with your credit card. Try this: Profile (that gear looking thing by Log out at the top right) - Payments - Set Pre-Approved Payments - Set Available Funding Sources This will give you a list of all the funding source...

I always pick my credit card rate. Even they are out to make money off you, but I don't want PayPal to take any more of my money. Even on smaller purchases. I bought something that was like 22USD, and PayPal wanted $28.91CAd and my card rate was like $28.10... 81 cents on a very small transaction. ...

Keeping in mind what Uunderhill said, if you do want to try a tube preamp, you could look for a model that isn't especially coloured, and that uses a true balanced circuit. The Sonic Frontiers Line series may work for you, or if you can find one, a 6H30 based Audio Research preamp would probably be ...
