Dumble Blue Capacitor
I was looking into late 80's/ early 90's ODS and noticed that frequently HAD used those blue capacitors. I have been on a hunt trying to find out what they are. I have seen an early amp (maybe 18X serial - don't recall exactly) which had a A/E stamp on the blue caps at the PI. The one on the picture...

Re: 50Hz vs 60Hz cycles - tonal impact?
I have been increasingly curious if the 50Hz to 60Hz will have tonal impacts on my Bandmaster. :wink: 40:56 https://youtu.be/rNvOUmwPiUQ Yep! I was looking at Kikusui 500M, which is the smallest unit, but it costs over GBP 2K. Hard investment but I am close to pulling the trigger as soon as I have ...

Re: 50Hz vs 60Hz cycles - tonal impact?
We commonly have variations of more than 3Vac in our mains power voltage at different times of day. Unless you can actively regulate the voltage, you're going to get changes unless the UK is much better at keeping it constant than we are in my part of the USA. to this. You are correct, in the UK th...

Re: 50Hz vs 60Hz cycles - tonal impact?
The easiest and cheapest solution would be to set up a bucking transformer to drop the 120V down to 117. This could be done using a 6.3V filament transformer rated for say 3A. The 50Hz vs. 60Hz makes the amp's power transformer operate closer to saturation, i.e. makes the core looks small. If it do...

50Hz vs 60Hz cycles - tonal impact?
I am on a rabbit hole recently. I own a '65 Fender Bandmaster, blackface. It was built to operate at 117V, 60Hz. I am based in the UK, with 240V mains and 50Hz cycles. My step down transformer gets my voltage down to 120V but does not change the cycles. I had ordered a Brown Box some time back to ge...

Re: 3rd Gen started
It lives!!! I thought I had a bad PT. When firing it up I got 340V on the plates and it sounded horrendous. After a lot of head scratching and calls to friends I pulled the power board only to realize I had missed a jumper between the incoming B+ and the reservoir caps. First impressions: It has a ...

I tried to order from them. The communication was very difficult. Even calling it was hard getting my orders in. I gave up after 6 monthsWhopperPlate wrote: ↑Wed Mar 01, 2023 4:15 pm They can make you anything https://guitarcabinetsdirect.com/

EVM 12L dust filter repair
Hi all, just wondering how would one repair the dust filter of a EVM 12L. Received the speaker today and left my 3 year old unattended for 3 seconds while I moved a can and boom, he managed to damage the thing, sigh

Re: Peavey Mace OT differences
Thanks Steve, yes the power tubes are 6x 6L6 on both iterations.
Makes sense! Thanks for the tip on the measurement, the only issue is that I do not have access to the 4/8ohms version
