human gear Animato ociliation problems!

[Yahoo67]

Hi guys ! I made a few of my own Animato boards and everything seems to work just fine, but when I try to max out the gain or volume pots if I get around pass 3 o clock the pedal will squeal very loud. :/

The rangemaster trimpot does not help ... I really got to turn it off if I what to go full gain. Because of this I am 99% sure that the problem is in the 2 piggy backed transistors. I don't own any nte102/103. I have been trying different Russian and Japanese germanium transistors but with no luck.

So I am wondering... Is it suppose to osciliate at full gain ? What hfe should I use ? Have any of you ever built one of these ? What was you experience with your builds ?

Thanks !
